How can I dynamically access control inside DataList ItemDataBound event when SeparatorTemplate is used for DataList control?
Usually I can dynamically access control (Label in this case) inside DataList ItemDataBound event using this code:
Dim Label1 As Label = e.Item.FindControl("Label1")Label1.Text = "sample text"
But when custom SeparatorTemplate is used for DataList control, then this code no longer works and produces this error:

How do I get values of controls inside datalist?
For example, if I have a label inside header template or item template or footer template?
Is there anyway to change property of label or any other controls inside those template as well?
I would really appreciate if anybody can just post a sample code or a helpful link about datalist? Would really like to know more about the events fired for datalist, itembound, itemcreating etc?

I am really frustrated when adding a linkbutton control to a dalalist server control. I use a datalist in my project and want to add the sort function to the list myselft. So I put a linkbutton control in the Headertemplete. However, the linkbutton is not added in the codebehind file automatically. when I define the linkbutton control explicitly in the codebehind and run the project. I always get an error due to the control always has a <undefined value>. Is it a well-known problem? I searched google and this forum not finding any thread that helps.
Anybody knows why?

I have a gridview bound with a SQLDataSource. I am using the Update feature of the SQLDataSource to update a SQL Server database with values entered into the gridview. However I am not getting it to work. I believe this is due to the controls that contain the user entries are not the gridview itself, but rather child controls within the gridview. I have been using the names of the actual controls but nothing happens. Upon submit, the screen returns blank, and the database is not updated. Here is some code:
