Is there a way I can pass this value back to the server and use it?
Text = Session("Company Name") Else lbl Company Name.
After investigation, it looks like the Selected Index Changed is not called because on the postback with update, the Drop Down List doesn't exists, therefore the event doesn't exist.
We have an application which creates maintenance screens based on an xml configuration file. This all works However, we have a new requirement to add Drop Down Lists to some columns to enforce data integrity.
I have therefore added the relevant xml, and when creating the grid, create the column as a Template Field and the Edit Item as a Drop Down List with its own Sql Data Source.
