Question

How to programmatically select GridView row so that "OnSelectedIndexChanged" event fires

Asked by: DanielBorson

I have a GridView that represents a list of Users. There's also a DetailsView to display a User's details. Both controls use the same ObjectDataSource control for data.

 In normal mode, when a user selects "Details", it selects the row, fires off the "OnSelectedIndexChanging" and "OnSelectedIndexChanged" events, and the details for a user are displayed in the DetailsView.

I want to be able to come into the page with a User's ID stored in Session, and to select that User's row in the GridView and display the DetailsView record for that user. This must all happen on Page Load.

I've searched online, but can find no solutions. I've attached my ASP.NET Code.

Thanks!
