Using The OnSelected Event Of SqlDataSource
May 18, 2008
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

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.

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?

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();
}

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?
Protected Sub SqlDataSource1_Inserted(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceStatusEventArgs) Handles SqlDataSource1.Inserted
Dim MailServerName As String = "alvexch01"Dim Message As MailMessage = New MailMessage
Message.From = New MailAddress("sender@email.com")Message.To.Add("receiver@email.com")
Message.Subject = "Near Miss"
Message.Body = "Test"
Message.IsBodyHtml = True
Message.Priority = MailPriority.NormalDim MailClient As SmtpClient = New SmtpClient
MailClient.Host = MailServerName
MailClient.Send(Message)
Message.IsBodyHtml = True
Message.Dispose()
End Sub

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.

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?

Recently we migrated our environment to 2012.
We are planning to implement Xevents in all the servers in place of Trace files and everything is working fine.
Is it possible to configure Extended event to trigger a mail whenever any event (example dead lock) occurs.
I have gone through so many websites but i never find.

I have been testing with the WMI Event Watcher Task, so that I can identify a change to a file.
The WQL is thus:
SELECT * FROM __InstanceModificationEvent within 30
WHERE targetinstance isa 'CIM_DataFile'
AND targetinstance.name = 'C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Backup\AdventureWorks.bak'
This polls every 30 secs and in the SSIS Event (ActionAtEvent in the WMI Task is set to fire the SSIS Event) I have a simple script task that runs a message box).
My understanding is that the event polls every 30 s and if there is a change on the AdventureWorks.bak file then the event is triggered and the script task will run producing the message.
However, when I run the package the message is occurring every 30s, meaning the event is continually firing even though there has been NO change to the AdventureWorks.bak file.
Am I correct in my understanding of how this should work and if so why is the event firing when it should not ?

But now i want to get the event properties through the Query analyzer...

We recently upgraded to SQL 2005 from SQL 2000. We have most of our issues ironed out however about every 1 minute there is a message in the Application Event log and the SQL log that states:
EVENT ID 18456 Login Failed for the users DOMAIN/ACCOUNT [CLIENT: <local machine>]
This is a state 16 message which I thought meant that the account does not have access to the default database. The account is actually the account that the SQL services run under.
Any ideas? We can't seem to figure this one out. We actually upgraded to 2005 from 2000 and had an error appear after every reboot that prevented the SQL Agent from running(This application has failed to start because GAPI32.dll was not found. Re-installing the application may fix this problem.) We did a full uninstall of SQL and reinstalled fresh and restored the databases from .bak files and that is when the EVENT ID 18546 started occuring every minute.
We don't have any SQL heavy hitters here so please be detailed with any possible solutions. That you very much for any help you can provide!

Event Type: Error
Event Source: Report Server Windows Service (MSSQLSERVER)
Event Category: Management
Event ID: 107
Date: 4/14/2008

User: N/A
Description: Report Server Windows Service (MSSQLSERVER) cannot connect to the report server database.
For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.
And also found an information in the error log saying that SQL Server Service started successfully immediately after this error occurred.
Is there any known root cause which makes the service restrat often ? How much is this impacting ?
Are there any methods to resolve this ?
I would be happy to get some more information on this.
Thanks.

i need some clarification here,i changed the CommandField for 'Delete" to the template field like this and its working well with the extender .<asp:TemplateField>
<ItemTemplate><asp:LinkButton ID="lnkDelete" runat=server Text="Delete" OnCommand=onCommand_deleter CommandArgument="Deleting" CommandName="Delete" ></asp:LinkButton>
<ajax:ConfirmButtonExtender ID="cnfDelete" TargetControlID="lnkDelete" runat=server ConfirmText="Are you sure you want to delete this ?" ></ajax:ConfirmButtonExtender>
</ItemTemplate>
</asp:TemplateField>
I am confused b/c
Earlier,i was handling the delete of a gridview row under OnRowDeleting event.Now its being handled by "onCommand_deletePlayer".Then why do I still need to handle onRowDeleting event?It gave me error,when i tried to avoid it.What exactly i shud code in OnRowDeleting. I am checking something like this rightnow in onRowDeleting,but this doesn't cancel the deletion despite of raising the messageif (gridView.Rows.Count <= 1)
{e.Cancel = true; lblMessage.Text = "You must keep at least one record // e.cancel doe NOT work,rows gets deleted despite the message,if delete link is clicked..}
Is there a way to stop the user from deleting the LAST and ONLY row from db for a given condition?thanks

We are trying to schedule a DTS package. If we run the package when the server is logged in the job works. If we logoff the server the job fails.
We looked in the NT Event log and we get a message from the SQLServerAgent that the job failed with Event 208. If we check the job Run History in the Next Run we get message 'Date and Time is not Available'. I should mention that the DTS pachage contains some mapping to drives on the server.
Any ideas? We have been struggling with this for a long time. Thanks.
