All we need is an easy explanation of the problem, so here it is.
I have a GridView containing template fields. Each template field contains a TextBox. Last column of the GridView contains SELECT command field.
On click of SELECT, I want to get the value of TextBox located in a cell of the selected row.
in Row_Updating event but it is not working.
I tried a similar variant of code in SelectedIndexChanged event of GridView but it gives error: Object Reference not set to an instance of an object.
