GridView SQLDataSource UserControl Problem

I was wondering if someone would be able to help me with the following:

Simply put, I have built an ASP.NET 2.0 WebUserControl (UC1). UC1
contains: A GridView which is bound to an SQLDataSource control (Stored
Procedure with 2 input parameters). The GridView contains 3 columns
(QuestionNumber , QuestionText, and a TemplateField). The TemplateField is
initially empty at design time and is populated with other UserControls which
are dynamically added and bound in the RowDataBound event of the GridView. I
have disabled the ViewState for the GridView as to ensure that the
RowDataBound event is fired every time. What I need to do is pass UC1, 2
parameters which the SQLDataSource will use to execute the stored procedure.
For this, I have added 2 public (Integer type) properties to UC1 so that they
may be specified dynamically.

I then drag-N-drop an instance of my user control (UC1) onto an empty page.
If I set the value of the 2 properties either in the Pre_Init event or the
control properties window in VS 2005, all works well. If I set the
properties in a Buttons’ Click event, nothing works. As I debug, I can see
that the value of the properties are 0. Its as though the assignment of
these properties in the Button’s Click event is fired too late for UC1 to
process them. In UC1, I use the SQLDataSource s Selecting event to assign
the parameter values
(SqlDataSource1 .SelectParamete rs("LanguageID" ).DefaultValue = Me.LanguageID),
and use the Init event to execute the SqlDataSource1. Select method. I am
sure I am doing something wrong with my events, etc…. In essence, I need to
pass SQLDataSource parameters to a user control and make it use those
parameters to execute against an SQL stored procedure

P.S.: Also, Is there a way to disable auto selecting/binding of a
form/SQLDataSource, etc… up until I specify .Selec
Regards,

Giovanni

I've chosen to implement the "optimistic concurrency" model in my application. To assist in that, I've added a ROWVERSION (TIMESTAMP) column to my main tables. I read the value of the column in my select, remember it, and then use it in the update. It works just fine when I have full control of the whole process. I want to do the same for my GridView/SqlDataSource combinations. I typically select from a view and update the corresponding...

Hello, Does anyone have an idea on how I can filter the data in the gridview control that was returned by an sql query? I have a gridview that works fine when I populate it with data. Now I want to look at that data and filter it based on what is in it. I know that this could have been done with data sets and data views in asp.net 1.1 but how is this done now in asp.net 2.0?

Dear Friends/Gurus, I have exhausted myself and have yet no solution to the following: I have an ASP.NET 2.0 Survey type application.

Each row in the GridView represents a question in a table (Ex.: "18. Satisfaction Level").

This seems like it should be simple to do but for some reason I have been unable to make it work. I would like to databind a SqlDataSource to a GridView during the click event of a button.
