Question

Hi Experts,

I have a gridview consists of template field.  I want to insert a new horizontally column between some of my gridview databound results and i did this, 

DataRow blankRow = dtPerformance.NewRow();

blankRow["performanceID"] = "";

dtPerformance.Rows.InsertAt(blankRow, 3);

how do i add a textbook/label in between the template field using the new blank row i created?

Hope you can help! Thanks.
