Expanding on Dennis R answer above      This will get the value based on the Heading Text  so you don t need to know what column   especially if its dynamic changing    Example setting a session variable on SelectedIndexChange       protected void gvCustomer SelectedIndexChanged object sender  EventArgs e                int iCustomerID   Convert ToInt32 Library gvGetVal gvCustomer   CustomerID             Session SSS CustomerID    iCustomerID         public class Library       public static string gvGetVal GridView gvGrid  string sHeaderText                string sRetVal   string Empty          if  gvGrid Rows Count  gt  0                        if  gvGrid SelectedRow    null                                GridViewRow row   gvGrid SelectedRow                  int iCol   gvGetColumn gvGrid  sHeaderText                   if  iCol  gt  -1                      sRetVal   row Cells iCol  Text                                  return sRetVal             private static int gvGetColumn GridView gvGrid  string sHeaderText                int iRetVal   -1          for  int i   0  i  lt  gvGrid Columns Count  i                          if  gvGrid Columns i  HeaderText ToLower   Trim      sHeaderText ToLower   Trim                                  iRetVal   i                                  return iRetVal

I suggest you use a HiddenField inside template field use FindControl to find this field   ie   ASPX                   lt asp TemplateField gt                       lt ItemTemplate gt                           lt asp HiddenField ID  hfFname  runat  server  Value   lt    Eval  FileName     gt     gt                       lt  ItemTemplate gt                   lt  asp TemplateField gt    Code behind  protected void gvAttachments RowDeleting object sender  GridViewDeleteEventArgs e                GridView gv1    GridView sender          GridViewRow gvr1    GridViewRow gv1 Rows e RowIndex              get hidden field value and not directly from the GridviewRow  as that will be null or empty          HiddenField hf1    HiddenField gvr1 FindControl  hfFname            if  hf1    null

Try changing your code to     Get the currently selected row using the SelectedRow property  GridViewRow row   dgCustomer SelectedRow      And you respective cell s value TextBox1 Text   row Cells 1  Text   UPDATE   based on my comment  If all what you are trying to get is the primary key value for the selected row then an alternate approach is to set  datakeynames  yourprimarykey   for the gridview definition which can be accessed from the code behind like below   TextBox1 Text   CustomersGridView SelectedValue ToString

I was looking for an integer value in named column  so I did the below   int index   dgv myDataGridView CurrentCell RowIndex   int id   Convert ToInt32 dgv myDataGridView  ID   index  Value    The good thing about this is that the column can be in any position in the grid view and you will still get the value   Cheers
