Question

I have a gridview and I would like to be able to programatically change the HeaderText of it’s columns (probably in the DataBinding event). I know this can normally be achieve with something like this:

myGrid.Columns[0].HeaderText = "My Header Text";

However, the gridview in question is actually nested within another gridview (via template column). So I can’t access it directly. I’m trying to use the FindControl method to access it, but so far that isn’t working. Any thoughts?

Capture that child grid in RowDataboud event of parent grid and here you can change the header text
Suppose myGrid is Parent Grid and ChildGrid is Child grid..

OnRowDataBound="myGrid_RowDataBound"

protected void myGrid_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {

           GridView ChildGrid = (GridView)e.Row.FindControl("ChildGrid");
           ChildGrid.Columns[0].HeaderText = "My Header Text";         
            .
            .
           ChildGrid.Columns[n].HeaderText = "My Header Text";                        
        }
    }
