Setting SqlDataSource Update Command And Parameters Dynamically C#

Aug 31, 2007

Hello all,

Ok, I finally got my SqlDataSource working with Oracle once I found out what Oracle was looking for. My next hurdle is to try and set the Update Command and Parameters dynamically from a variable or radiobutton list. What I'm trying to accomplish is creating a hardware database for our computers by querying WMI and sending the info to textboxes for insertion and updating. I got that part all working nicely. Now I want to send the Computer name info to a different table column depending on if it is a laptop or desktop. I have been tossing around 2 ideas. A radiobutton list to select what it is and change the SQL parameters or do it by computer name since we have a unique identifier as the first letter ("W" for workstation, "L" for Laptop). I'm not sure what would be easiest but I'm still stuck on how this can be done. I posted this same question in here a few days ago, but I didn't have my SqlDataSources setup like I do now, I was using Dreamweaver 8, it is now ported to VS 2005. Below is my code, in bold is what I think needs to be changed dynamically, basically i need to change DESKTOP to LAPTOP...Thanks for all the help I've gotten from this forum already, I'm very new to ASP.NET and I couldn't do this without all the help. Thanks again!

 

<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:CAT %>"ProviderName="<%$ ConnectionStrings:CAT.ProviderName %>" SelectCommand='SELECT * FROM "COMPUTER"' UpdateCommand="UPDATE COMPUTER SET DESKTOP = :DESKTOP, TECH = :TECH, SERVICE_TAG = :SERVICE_TAG WHERE USERNAME=:USERNAME">

<UpdateParameters>

<asp:ControlParameter Name="USERNAME" ControlId="txtUserName" PropertyName="Text"/>

<asp:ControlParameter Name="SERVICE_TAG" ControlId="txtServiceTag" PropertyName="Text"/>

<asp:ControlParameter Name="TECH" ControlId="txtTech" PropertyName="Text"/>

<asp:ControlParameter Name="DESKTOP" ControlId="txtComputerName" PropertyName="Text"/>

</UpdateParameters>

</asp:SqlDataSource>

SqlDataSource SelectCommand - Dynamically Setting The Name Of The Table?

May 7, 2007

Can you dynamically set the name of the table in the SelectCommand section of the SqlDataSource? (If it is relevant, I code in C#)
 For example,
<asp:SqlDataSource runat="server" ID="SqlDataSource1" ConnectionString="<%$ ConnectionStrings:Test-MySQL %>" ProviderName="<%$ ConnectionStrings:Test-MySQL.ProviderName %>" SelectCommand="SELECT * FROM TestTable">
I would like to replace 'TestTable' with the name of a table that is extracted from a string array in the code-behind.
Appreciatively,Peter

Dynamically Adding New Parameters To SQLDataSource

Dec 28, 2007

CancelSelectOnNullParameterHi,Suppose I have a SQLDataSource with a
SelectCommand="SELECT * FROM STOCKS WHERE USER=@USER ORDER BY STOCK_NAME"
and @USER is set as a session parameter. No problem till this part, but in some postbacks, I wish to add a new WHERE criteria to my SQL, so I do:DSSQL.SelectParameters.Add("@STOCK_NAME", "ABC123");
DSSQL.SelectCommand = DSgvStoklar.SelectCommand.Replace(" ORDER BY ", " AND STOCK_NAME LIKE @STOCK_NAME+'%' ORDER BY ");
gridViewDS.DataBind();
and wish that my SelectCommand is modified and a new parameter is added.
The SQL is modified, however -I guess- new parameter is not added, so I get "Must declare the scalar variable "@STOCK_NAME" error.
How can I solve, any ideas?

Oct 31, 2007



Hi all
I hope someone can help me on this issue:
I am designing dynamical reports, that are abel to run in four different languages - so far everything works just fine for me (I select my headers and labels from a database). Only problem is the prompt text for report parameters. How can I set this text dynamically?

E.g. I have a parameter where the user selects a storage - this prompt should be "Storage: " in the English report and "Lager: " in the Danish report. I have absolutely no idea how to fix this.

I am greatful for any help.

Hi,How do I set the parameters of an SqlDataSource programatically?I have tried the following...dsDraftBudgetPI.SelectParameters.Add(new Parameter("@person_id", TypeCode.Int32, pID.ToString()));But that didn't work.  I already have the parameter defined at design time so I don't need to create one I just want to set its value and then bind it to a ListBox to display the result.Thanks,Scott

Setting SqlDatasource Parameters From TextBox

Feb 17, 2008

I have a sqlDatasource with 3 parameters based on the input of 3 text boxes on the page. The datasource returns sales details for a company based on a from and to date. I am attempting to set the value of the 3 parameters in the Selecting event of the datasource control but I'm not getting any data back. If I set the values literally then I get data back. Also when I step through the code I can see the 3 parameters getting their values from the textboxes and the drop down list as they should. This is driving me insane as I'm new to .net and just can't see what is stopping me retrieving the data when using the form fields to set the datasources parameters. Below is the aspx and the code behind for the page.

Passing '% Variable %' To SqlDataSource Through E.Command.Parameters

Feb 23, 2008

 Hello all,I'm writing a site with one page that uses the session variable (User ID) to pick one user ID out of a comma separated list in the field Faculty. The default parameterized query designed in the SqlDataSource wizard only returns lines that contain an exact match:SELECT * FROM tStudents WHERE ([faculty] = @faculty) The query: SELECT * FROM tStudents WHERE ([faculty] LIKE '%userID%') works as I need when I hard code the query with a specific user ID into the SqlDataSource in the aspx page.  It will not work if I leave the @faculty parameter in it:SELECT * FROM tStudents WHERE ([faculty] LIKE '%@faculty%') e.Command.Parameters works to replace the @Faculty with a user ID, but again, adding the single quote and percentage sign either causes errors or returns no results.  I've tried several variations of:         string strEraiderID = "'%" + Session["eRaiderID"].ToString() + "%'";        e.Command.Parameters["@faculty"].Value = strEraiderID;no results are returned, not even the lines returned with the default select query.How do generate the equivalent of SELECT * FROM tStudents WHERE ([faculty] LIKE '%userID%') into the SqlDataSource? Thanks much!

Stored Procedure Parameters Update Dynamically

Sep 22, 2014

I set up a stored procedure. My stored procedure has 8 variables declared at the beginning like this:

===========================
declare@IncurredDateStartsmalldatetime
,@IncurredDateEndsmalldatetime
,@PaidDateStart_CUsmalldatetime
,@PaidDateEnd_CUsmalldatetime
,@PaidDateStartsmalldatetime
,@PaidDateEndsmalldatetime

[Code] ....

All of these dates are based on the update of our data warehouse. This stored procedure runs a 5 step process and produces data for 8 - 10 monthly reports.

I was wondering if these variables can be updated dynamically and if they can how it is done.

How To Trigger The Update Command Of The SQLDataSource

Jun 13, 2006

Hi - I'm using .net2, and have a gridview, populated by a SQL Datasource (Edit, Insert, Delete, Select).
Like we all used to do with the datagrid, I've added text boxes into the footer, and a link button, which I'd like to use to fire the Update command.
How do I get the link button to trigger the update command?
Thanks, Mark

SQLDataSource Update Using Parameters Not Working

Jul 10, 2006

I'm passing a parameter to a stored procedure stored on my sqlserver, or trying to atleast.  And then firing off the update command that contains that parameter from a button.  But it's not changing my data on my server when I do so.
I'm filling a dropdown list from a stored procedure and I have a little loop run another sp that grabs what the selected value should be in the dropdown list when the page loads/refreshes.  All this works fine, just not sp that should update my data when I hit the submit button.
It's supposed to update one of my tables to whatever the selected value is from my drop down list.  But it doesn't even change anything.  It just refreshes the page and goes back to the original value for my drop down list.
Just to make sure that it's my update command that's failing, I've even changed the back end data manually to a different value and on page load it shows the proper selected item that I changed the data to, etc.  It just won't change the data from the page when I try to.
 
This is what the stored procedure looks like:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
ALTER PROCEDURE [dbo].[UPDATE_sp] (@SelectedID int) AS
BEGIN
UPDATE [Current_tbl]
SET ID = @SelectedID
WHERE PrimID = '1'
END

Update Command In SQL DateSource Mixing Up My Parameters

Dec 14, 2007

I have an update command with 7 parameters, but at run time the order to the parameters gets mixed up.
I'm using a stored procedure. At first I have the command type set to text, and was calling it using EXEC spName ?,?,?,?,?,?,?
I then named each of the parameters and set their sources.  The parameters are like this (samepl name, then source, then type):
A : QueryString - intB: Control - intC: Control - intD: None - intE: None - decimalF: Control - datetimeG: Control - datetime
At run time I was getting an error that an integer couldn't be converted to date time. So I put a breakpoint in the Updating event and then looked at the parameters prior to update.
This is how they looked (Parameter index, paramter name):
[0] A[1] B[2] D[3] E[4] F[5] G[6] C
It didn't maek any sense. Do, I deleted all of the paramters and readded them. That didnt' work. Then I changed the command to StoredProcedure and refreshed the parameters from the stored proc and it brought them in the right order, but the problem remains the same.
I looked at the page source, and there are no indexes in the page source, but the parameters are listed in the proper creation order, as follows:<UpdateParameters><asp:QueryStringParameter Type="Int32" Name="PROJ_ID" QueryStringField="pid"></asp:QueryStringParameter><asp:ControlParameter PropertyName="SelectedValue" Type="Int32" Name="TASK_UID" ControlID="fvTask"></asp:ControlParameter><asp:ControlParameter PropertyName="SelectedValue" Type="Int32" Name="ASSN_UID" ControlID="gvResources"></asp:ControlParameter><asp:Parameter Type="Int32" Name="RES_UID"></asp:Parameter><asp:Parameter Type="Double" Name="Work"></asp:Parameter><asp:ControlParameter PropertyName="Text" Type="DateTime" Name="Start" ControlID="TASK_START_DATETextBox"></asp:ControlParameter><asp:ControlParameter PropertyName="Text" Type="DateTime" Name="Finish" ControlID="TASK_FINISH_DATETextBox"></asp:ControlParameter></UpdateParameters>
No mater what I do, at run time ASSN_UID is always the last parameter. I've also run a SQL trace to see how it is actually being executed, and sure enough, its passing the value for ASSN_UID as the last parameter, which obviously doesn't work.
Any ideas as to why this would happen or how to fix it?
(I guess I can reorder the patameters in the stored proc to match how they are being passed, but still, that wouldn't be a very comfortable solution, since it could perhaps revert at some point or something)

Setting DTS Connction Object Dynamically

May 12, 2006

Hi:

I have posted concerning this-I don't mean to double post but I have
isolated the problem and have new information. (and I'm desperate!!) Please direct me to a DTS forum if this is not the place for this, I didn't see one.

I am trying set the data connection object (ODBC to Sybase) twice in
the same package but the Data Pump Tasks that use this connection don't
seem to be using the new setting in the connection after the second
time it is set, although at the end of the package I can see that the
connection has been set. The pumps just use the original connection a
second time instead of using the 2nd connection.

Here is the progress:
1. SQL Task1: Gets server information from a SQL Server table, and sets
it to a recordset global variable in the DTS.
2. ActiveX Task1: Begins loop, and sets the connection to server2 and
sets sql of datapump tasks
3. Several data pumps run.
4. ActiveX Task2: just loops around to ActiveX Task1
5. ActiveX Task1: Sets the connection object to server2 (msgbox tells
me this happens successfully)
6. The datapumps continue to use server2(??)
7. Package finishes succesfully
8. I right click on first datapump and do a "execute task". It executes
using server2, which for some reason it did not do during execution of
the entire package.

The loops works fine (as I have gotten it from you Allan), it clearly
goes through twice when I have specified two servers (I can see the
data in the resulting table is doubled from the source server, and I
can see it in the progress window going through the data pump steps
twice). After, if I run the data pump tasks by right clicking and doing
an "execute task" then it works using server2 was set.

I put a msgbox in the ActiveX Task1 to confirm the server is being set
correctly.

Any ideas here? Is there some other property I need to set? Is it a
setting with the Data Pump task? This all seems very weird-I feel like
I must be missing something obvious.

Here is the part of the code of ActiveX Task 1 (only part) that sets
the connection (let me know if you want to see the package):

Dim pkg
Dim SCCScon
Dim objRS
Dim SQLStatement

set pkg = DTSGlobalVariables.Parent
set SCCScon = pkg.Connections("Connection_Name")

set stpEnterLoop = pkg.Steps("DTSStep_DTSDataPumpTask_1")
set stpFinished = pkg.Steps("DTSStep_DTSActiveScriptTask_5")

Set objRS = DTSGlobalVariables("gvDataSources").Value

stpFinished.DisableStep = true
stpEnterLoop.DisableStep = false
stpEnterLoop.ExecutionStatus = DTSStepExecStat_Waiting

msgbox "DSN is now: " & SCCScon.DataSource

SCCScon.DataSource = objRS.Fields(1)
SCCScon.UserID = objRS.Fields(2)
SCCScon.Password = objRS.Fields(3)

msgbox "Now I've set the DSN and it is now: " & SCCScon.DataSource

Thanks as always,

Error at Caller Package: the filename is not valid. the filename is a device or contains invalid characters.

Anyone know why?

Configuring Dynamically An SqlDataSource

Jan 4, 2008

I have several Sql Tables, each containing more than 100 fields, on which I need to perform display operation through GridView, Insert and Update through an array of dynamically created and databound TextBoxes.
I would like to use a single page to manage all Sql Tables on the basis of the name of the specific one invoked by the user.
In order to achieve that, I need to  dynamically configure the SqlDataSource Web Control present on the page for each Sql Table. In particular I need to generate at runtime the InsertCommand and the UpdateCommand.
On how to do it I have no idea.

Setting Default Value Of A Report Parameter Dynamically

Jan 26, 2007

Hi all,

Does sombody have experience on dynamically set or change the default value of a report parameter?

Assuming: report parameters p1, p2, p3, p4 have been set up(and have their default value 'all') with the creation of the report1; report browseing is through reportviewer that embedded in the web application; datasource is datacube

What I want to do: based on the login user of the my web application, set default value of p1 as the user's username.

What I did is:

Microsoft.Reporting.WebForms.ReportParameter reportParam = new Microsoft.Reporting.WebForms.ReportParameter("P1","Mary");

ReportViewer1.ServerReport.SetParameters(new Microsoft.Reporting.WebForms.ReportParameter []{ reportParam });

what I got when reveiw the report:

P1 has no default value, and p2, p3, p4 greyed and could not choose value from them.

Any idea and suggestion will be pre-appreciated!

Dynamically Setting Connection String Depending On Server_name?

Apr 18, 2008

I need to make my site aware of which server_name it is loading from so it uses a different connection string. (have dev + prod servers for web/sql)Currently my connection string is in web.config as follows:  <connectionStrings>      <!-- Development and Staging connection string -->          <add name="myconnection" connectionString="server=myserver; user id=mysuer; password=mypassword; database=mydatabase" />   </connectionStrings> I need to make sure the 'name' is the same for both connection strings since that is how the rest of my site looks for it.  However, I'm not sure how to get both in here with some sort of 'if/then' statement to determine which one to use.I've heard it could be done in global.asax with something similar to the code below, but I dont know how to assign a 'name' to a connection string for that type of setup. Sub
Session_OnStart  ServerName =
UCase(Request.ServerVariables("SERVER_NAME"))  IF ServerName = "prod.server.com" THEN   ...Set Prd string...  ELSE   ...Set Dev string...  END IF  End
Sub

Setting Expressions In Datareader's SQLCommand Property Dynamically

Sep 19, 2006

Hi all,

I have been playing with integration services for a few days and at the moment, its up there with my list of software that I find ......painful.

What I am trying to do is read different tables from my one SQL database, then populate my Access database with its data.

I have put a foreach loop which goes through a collection SQL statements that I have entered into it. It first assigns it to a string variable called tablenameVar which contain statements such as "Select * from Terminals". Then the datareader is supposed to execute it based on the connectstring which never changes, and the SQLCommand value which I passed using the variable @[User::tableName]. However when I try to run it, I'm getting this error.

TITLE: Package Validation Error

Does anyone have an idea of what I should do? or maybe a better way to do it? I appreciate you guys for taking a time to look at this.

SqlDataSource: How To Give A Dynamically Defined SelectCommand Parameter

Dec 12, 2006

Hi all
I have a cms-page where i want to display various entry-categories like news etc....I want to define which kind of entries should be shown by a parameter in the URL (e.g. cms.aspx?category=news). So far everything is OK.
To display the entries actually I'm using the following SqlDataSource:
<asp:SqlDataSource ID="SqlDataSourceCMS" runat="server" ConnectionString="......."SelectCommand="SELECT * FROM [cms] where category = news"></asp:SqlDataSource>
What i need, is to set the category which i want to show dinamically, like with a variable.
Does anybody know how i can set something like a variable in the SelectCommand property of the SqlDataSource?
