GridView's NewValues and OldValues empty in the OnRowUpdating event

Question

I have the GridView below. I am binding to a custom datasource in the code behind. It gets into the \"OnRowUpdating\" event just fine, but there are no NewValues or OldVal

Answer 1

You need to check the IsPostback in the form load. When the gridview's Update did the postback, it first refreshed with the old values. Use IsPostback to prevent this:

If Not IsPostback Then 

   ' Data bind here

End If

This way, it will not overwrite the "new" gridview values
