hi,
i want to execute a finctionX() based on the returned resultset of SQLDataSource. For example, if the SELECT command returns nothing based on a specific search criteria then I want to execute functionX(). Currently, I have a string that displays "No Result" in the GridView in such case.
How to catch the resultset of SQLDataSource?

Hi all...I've set the DataSourceMode = SqlDataSourceMode.DataSet, and did a .Type return and found that it is actually returning a DataView. A component I am trying to avoid rewriting....requires a dataset that loops through the table, does some cool formatting to a datagrid and then rebinds.Here's the code that I'm trying to send the dataset to....maybe there's just a couple of changes that could make it work with a DataView? int i = 0; string prevsub = ""; while (i <= ds.Tables[0].Rows.Count - 1) { DataRow dr = ds.Tables[0].Rows[i]; string sub = dr["SubHeading"].ToString(); if (sub != prevsub) { prevsub = sub; DataRow newrow = ds.Tables[0].NewRow(); newrow["Title"] = "SubHeading"; newrow[columnName] = dr[columnName]; ds.Tables[0].Rows.InsertAt(newrow, i); i++; } i++; }

Hi all,
hope anyone can help me on this one.
I have a parameterized report based on a MDX query (so no drag and drop of filters and fields).
Now i have to ad a parameter. So i open the query parameter dialog box and i ad my parameter.
when i click ok , my dataset becomes empty , resulting in an error on my report saying that the fields on the report cannot by found and should be in the scope of the dataset.
Has anyone experienced this problem before, or am i forgetting something here?
thanks in advance

I need to display something like "Results x-y of z." The problem is, I can't figure out how to get the right value for z.I am using SqlDataAdapter and Fill()ing a DataSet with subset x through y of the result set. How can I get the right value for z?

I want to know if there is an event in profiler can catch web application name. If yes, which one? For example, there is SP named sp_storedprocedure that is called by www.web.com and www.web.com/forumdisplay.php?f=23. I want create a profiler trace that can catch www.web.com or www.web.com/forumdisplay.php?f=23 calling sp_storedprocedure. Any suggestion is great appreciated.

hello everyone
I'd like to know if there is a way to catch the error messages when a tasks fails, that's because i's like to store every message on a user variable, so i could log all of them later, I was thinking that it may be possible with the event handlers, could it be?

I'm using Report builder 3.0 to create a report. In the design, datatset query i have a sql to calculate difference between two dates (date1-date2) as processing time. I have this (processing time ) ONLY in my ORDER by clause and when i execute the statement it does exactly what i was looking for , however when i run the report the sort order is not delivered. I checked each column tablix properties and the sorting order is set for Processing Time.

We have a package that runs on 3 servers, all based in different countries and time zones. Each package does logging to a common SQL Server based in New York. (We log to the same server to make monitoring of the package run results easier.) We expect that our overseas servers will occassionally fail to make a database connection and have coded a Try/Catch block in our Script task to ignore errors that occur when attempting the SQL Server logging.
The problem is that the OnError event handler defined at the package level is being called whenever a server fails to make a database connection. The Catch block appears to not be called at all. I've included below the short method that does the SQL Server logging. The "Dts.Log" line logs to a SQL Server and usually works. However, when it fails, the "WriteEventLogEntry" method is supposed to be called to write an error to the server's event log. (I haven't included the "WriteEventLogEntry" code but it works fine when called elsewhere in the package to do our non-error event logging.)
Public Sub WriteSqlServerLogEntry(ByVal logMessage As String, ByVal dataCode As Integer, ByVal dataBytes() As Byte, ByVal rowsInserted As Integer)
Try
Dts.Log(logMessage, dataCode, dataBytes)
Catch ex As Exception
WriteEventLogEntry("An exception was thrown while attempting to log the following message to the SQL Server provider: " + logMessage, EventLogEntryType.Error, rowsInserted)
End Try
End Sub
Shouldn't a Catch block prevent the OnError event from being raised? How can I change my package to ignore all errors that occur when attempting SQL Server logging?
Gracias!

I have a sqldatasource and I allow deletions that could cause a constraint violation. I want to capture this error however, I am using the sqldatasource bound to my datacontrol. I dont know where to catch the error. Unfortunately there is no OnError event for the control... There is no code behind for this at this time. I am hoping there is a way to do this without completely rewiring everything.
My thanks in advance,
Hi !
Is it possible to not display a report when the dataset is empty and in this case show a message to tell that there is no data to display?
Thanks !
I'm querying my database with a datetime constraint, only picking up records newer than the last ETL. Although I doubt it would ever happen I was going to put a check in the data flow to trap the case when NO rows were read due to inactivity in the OLAP. I set up a row count and tried to trap it. Apparently if you use an OLE DB source to get a result set and that result set is empty, the program flow bypasses everything and keeps running until it hits something causing an error, like an SQL Insert or Update command.
Is there any way to trap this condition? Currently it is going to cause the program to fail which will cause a snapshot restore (after kicking everyone out of the database).
Thanks.
Hi all,
Can we get the event properties by using a query?
Are there any extended stored procuder to get the above?
Scenario:
>Desktop>Right Click on My Computer
>Go to Manage and click
>Expand System Tools
>Expand Event Viewer
>Application
click on one event.We can get the log info which is the manual procudure.
But now i want to get the event properties through the Query analyzer...
Any help would be great?
Thanks,
HI,
I am using XmlDataDocuments returned by webservices and query in the reports to populate the reports.
The issue I have is if the dataset used to populate the XML document has any nulls or empty spaces in any field the whole column or row is missing in the data generated by my query in the Reports. Sometimes the whole data is not being returned to the reports.
Sample query I use
<Query>
<SoapAction>http://xxxx.webservices.org/SelectReportRegisters</SoapAction>
<Method Namespace="http://xxxx.webservices.org/" Name="SelectReportRegisters">
<Parameters>
<Parameter Name="p_registerType">
<DefaultValue>All</DefaultValue>
</Parameter>
<Parameter Name="p_registerName">
<DefaultValue>All</DefaultValue>
</Parameter>
<Parameter Name="p_asOfDate">
<DefaultValue>7-1-2009</DefaultValue>
</Parameter>
</Parameters>
</Method>
</Query>
I have tested the webservice with sample data and it works well, returns data.
I use the ISNULL() in my stored procedures to avoid nulls but with empty strings, replacing them with a default value in the managed code is expensive and slows down the reports.
Is there some feature I am missing because of which nulls and empty strings are causing this problem.
I am using Reporting services 2005.
Any pointers will be truly appreciated.
I have two SQLDataSource controls on my page that are dynamically fed an SQL SELECT statement. I was thinking that the best way to do this was to give it the select statement that it needs inside the OnSelecting event. Here is the revelent code.
<asp:SqlDataSource OnSelecting="GetData_Selecting" ID="DS1" ConnectionString="<%$ ConnectionStrings:MyConnectionString %>" ProviderName="<%$ ConnectionStrings:MyConnectionString.ProviderName %>" runat="server" SelectCommand="" />
<asp:SqlDataSource OnSelecting="GetData_Selecting" ID="DS2" ConnectionString="<%$ ConnectionStrings:MyConnectionString %>" ProviderName="<%$ ConnectionStrings:MyConnectionString.ProviderName %>" runat="server" SelectCommand="" />
protected void GetData_Selecting(object sender, SqlDataSourceSelectingEventArgs e)
{
System.Diagnostics.Debug.WriteLine("Getting Data...");
switch ((sender as SqlDataSource).ID)
{
case "DS1":
if (Checkbox1.Checked)
{
e.Command.CommandText = "SELECT * FROM table1 WHERE " + BuildQuery(getMylarColumns(), SearchBox.Text);
DS1Panel.Visible = true;
}
break;
case "DS2":
if (Checkbox2.Checked)
{
e.Command.CommandText = "SELECT * FROM table2 WHERE " + BuildQuery(getFlatFileColumns(), SearchBox.Text);
DS2Panel.Visible = true;
}
break;
}
The problem with this is that the GetData_Selecting method is never executed and thus when I try to execute the query the page PostBacks and nothing happens. Putting equivalent code in the Page_Load method works fine, however I believe having the code execute on each PostBack is the reason I'm having another problem sorting the data in the DataGrids these controls are bound to.
Why is the function never being executed? Is this the ideal way to handle the inclusion of the query in the SQLDataSource?
Hello,
on my site I have a sqldataSource and a listview working together. But now after selecting data from my database and before binding data to the listview i want to change the data. For example: I select an image filename and i want to check if the file exists, and if it not exists i want to change this filename. How can I do that. My Idea was to use the OnSelected Event of the datasource, but i don't know how to acces the selected data ...
I hope someone can help me

(Newbie). I'm trying to: 1) check if the SELECT command has returned any records, and 2) put a msg box on the screen if there are no records returned from the SELECT query. The type of code I'm heading towards is: (but it's wrong). Thank you in advance for your C# code suggestion.
protected void SqlDataSource1_Selected(object sender, SqlDataSourceStatusEventArgs e)
{if (SqlDataSource1.SelectParameters.Contains is "") then
MessageBox.show ("There are no records available") ;

O.S. = Windows Small Business 2003
DB = SQL 2000 Server with SP3a
No windows or third party firewalls that are set up.
Problem:
When performing a Link Table in MS Access 2003 it runs into this error message "The Microsoft Jet Database engine could not find the object 'zstblSetup' (the name of our table). Make sure the object exists and that you spell its name and path name correctly.
But when we try to another server but at this time the SQL 2000 is patch with SP4, the link table works fine in Ms Access 2003. So we decided to use SQL Profiler to trace the cause of the problem. It so happen when sp_columns N'zstblSetup' is called no result is returned. Going through the code in sp_columns, it calls spt_datatype_info. When calling spt_datatype_info, again no record is returned. We suspect that spt_datatype_info is the culprit of the problem that's why Link Table in MS Access 2003 doesn't work.
Calling the sp_columns and spt_datatype_info into the working server that I mentioned aboved can return results. The way I understand it spt_datatype_info holds the SQL data type info.
My question is if we apply SP4 in the server that is problematic will this problem be resolved? Or are there any possible reason to solve this problem?
Greetings,
When using Inserting event of SqlDataSource ASP.NET gives me an error when I reference InsertParameter by Name
An SqlParameter with ParameterName 'CreatedByEmployeeId' is not contained by this SqlParameterCollection.
However, when I reference parameter by index everything works.
Is this a bug or I'm doing something wrong?
Here's the code:
<asp:SqlDataSource ID="dsRole" runat="server" ConnectionString="<%$ ConnectionStrings:SecurityConnectionString %>" DeleteCommand="spDeleteRole" InsertCommand="spAddRole" SelectCommand="spGetRole" UpdateCommand="spUpdateRole" DeleteCommandType="StoredProcedure" InsertCommandType="StoredProcedure" SelectCommandType="StoredProcedure" UpdateCommandType="StoredProcedure">
<DeleteParameters>
<asp:Parameter Name="RoleId" Type="Int32" />
</DeleteParameters>
<UpdateParameters>
<asp:Parameter Name="RoleId" Type="Int32" />
<asp:Parameter Name="RoleName" Type="String" />
<asp:Parameter Name="RoleDescription" Type="String" />
<asp:Parameter Name="UpdatedByEmployeeId" Type="Int32" />
</UpdateParameters>
<InsertParameters>
<asp:Parameter Name="RoleName" Type="String" />
<asp:Parameter Name="RoleDescription" Type="String" />
<asp:Parameter Name="CreatedByEmployeeId" Type="Int32" />
</InsertParameters>
<SelectParameters>
<asp:ControlParameter ControlID="GridView1" Name="RoleId" PropertyName="SelectedValue" />
</SelectParameters>
</asp:SqlDataSource>
When using parameter name, I get an error:
Protected Sub dsRole_Inserting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceCommandEventArgs) Handles dsRole.Inserting
e.Command.Parameters("CreatedByEmployeeId").Value = Internal.Security.GetEmployeeIdFromCookie(Page.Request.Cookies)
End Sub
When using index instead of name, there's no problem:
Protected Sub dsRole_Inserting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceCommandEventArgs) Handles dsRole.Inserting
e.Command.Parameters(2).Value = Internal.Security.GetEmployeeIdFromCookie(Page.Request.Cookies)
End Sub
Hi
In the page load of my webpage I call a databind for a gridview.
It generally calls this event handler :
protected void SqlDataSource1_Selected(object sender, SqlDataSourceStatusEventArgs e)
However sometimes (seemingly randomly) it doesn't.
Any ideas?
Thanks
p
protected void Page_Load(object sender, EventArgs e)
{
...
if (searchText != "")
SqlDataSource1.SelectParameters["search"].DefaultValue = searchText;
else{
SqlDataSource1.SelectParameters["search"].DefaultValue = "";
GridView1.DataBind();
}
Hi All - I've got a simple gridview/sqldatasource page, but the sqldatasource_onSelected event isn't firing.
heres the parameters <SelectParameters>
<asp:QueryStringParameter Name="LicenceID" QueryStringField="LicenceID" Type="string" />
<asp:QueryStringParameter Name="SiteID" QueryStringField="SamplingSiteID" Type="string" />
</SelectParameters>
either or both parameters may be null (ie. not in querystring ) .
If only one of the selectparameters is null, and I remove it, the event fires!!!
The parameters in the stored proc are optional(ie. default = NULL) and it works fine if I test it in SQL .
Whats going on? If there's some error happening, why no error raised? if there are no records returned, the onselected event should still fire shouldn't it?

Hi,
I have a SqlDataSource whose select statement uses parameters from the selected row on a gridview on the page. So when a row is selected in the gridview, I want the SqlDataSource to do a select using the new parameters, and then I want to inspect the number of rows returned. If 0, I want to set a FormView to insert mode, if >0 I want to set the FormView to edit mode.
The "SqlDataSource2_Selected" sub never fires, so I cannot retrieve the number of rows returned. How can I deal with this? I would like the SqlDataSource to execute a Select each time the Gridview selected row changes. What could prevent "OnSelected" from firing?
I do have "OnSelected="SqlDataSource2_Selected" within the SqlDataSource tag.
Thanks in advance for any help with this.
This is probably an easy one.
What is best way to determine if a SqlDataSource is empty (i.e. the query produced no results) in the CodeBehind?
I'm using this:
if (SqlDataSource1.SelectCommand.Contains(String.Empty))
{
//Add code for scenario here.
}
It seems to work, but something just doesn't feel right about it for some reason.
Thanks
I have an app which uses SQLDataSource to update the information to database (SQL Server 2000). Is there a way to trim the input of users somehow (blank lines) ? For example if I have an Comments-textarea on my form and users enter text to it, can I somehow take out the extra blank lines out of that textarea before submitting the data to database ? I know how to do this programmatically, but was just wondering if this could be done when using SQLDataSource-control.
I'm using DataReader to extract the information from database to an CSV-file. Because of the blank lines, occasionally CSV are really messed up because of that. Is there a way to remove the blanklines when iterating the DataReader values ?
Hello guys,
MS SQL server 2000 behavies strange with big queries that involves relatively large number of tables:
If I just enumerate columns I want to receive, the result set is empty. Adding * to the column list without making any change to where clause seems to solve the problem but I guess it's not the best practice.
The most amazing is that this behavior is not stable, so I suppose there's something to deal with server itself, not the application.
Has anybody suffered this problem and what solution was adopted?
Thanks for any information you can provide.
Hello
I have a piece of VB.NET code that generates an email on the SqlDataSource Inserted event. It appears to be executing twice because it is sending two emails. If I place the code on any other event, it just sends the one email. Does any have a suggestion on how to handle this?

I have an event:
Private Sub SqlDataSourceIncome_Deleted(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceStatusEventArgs) Handles SqlDataSourceIncome.Deleted
Dim command As SqlClient.SqlCommand
command = e.Command
If command.Parameters("@nReturnCode").Value <> 0 Then
DROPDEAD()
End If
That fires from:
<DeleteParameters>
<asp:Parameter Name="nDeletebyId" Type="Int64" />
<asp:Parameter Name="nOtherId" Type="Int64" />
<asp:Parameter Direction="Output" Name="nReturnCode" Type="Int64" />
<asp:Parameter Direction="Output" Name="nReturnId" Type="Int64" />
</DeleteParameters>
End Sub
When I:
GridViewIncome.DeleteRow(GridViewIncome.SelectedRow.RowIndex)
But nReturnCode is ALWAYS NULL... I even did a stored procedure that just:
ALTER PROCEDURE [dbo].[sp_nDeletebyId]
@nReturnCode bigint output,
@nReturnId bigint output AS
SET @nReturnCode = 0
SET @nReturnId = 0
And STILL got nothing but the NULLS... the insert & update stuff works fine, with identical code... it's just the DELETED event that I can't seem to knock. Has anyone seen this before? The above sample stored proc did return 0 when executed one the server...
and, BTW, the row is deleted!

Hello, I want to loop through the first 10 records that are showing in a gridview with several pages that is populated by a sqldatasource. I can loop through the sqldatasource and get the list of values, but I'm doing something wrong because the 10 records it prints out are not the same 10 records the user sees in the gridview...They can click a search button which changes the sort, and they can click on the column headings to change the sort order.
Where's the best place to put the looping code? I need the result to be the same as what the users sees.

Dear sir or madamI have a problem related to using sqldatasource and dataset.I heard that using dataset is faster than using sqldatasource,but I think that in sqldatasource have a DataSourceMode property allowing user to choose to use with dataset or datareader.Now,I still wonder why they said that dataset is faster than sqldatasource. I look forward to hearing from you.Thank you in advance.Best wishes,
