                txtid.Text = "name"+ProductName+"department"+description+"code"+productID;
       
    }

Answer 1

Ok, so we want to get/grab/fetch data from a given row in the grid. And in this case, we want the first row.

For data bound fields/columns, you have to use the .cells collection of the given row. (for templated controls (say standard asp.net text boxes, you have to use find control).

So, to get that data, you can use this: 0 would be image, 1 would be Description 2 would be ProductName 3 would be productID

Hence:

GridViewRow gvRow = GridView1.Rows[0];

txtid.Text = "name" + gvRow.Cells[2].Text
   + "department" + gvRow.Cells[1].Text + "code" + gvRow.Cells[3].Text;
