Still the same issue.. I have already tried what you have suggested. I am using Datagrid and not Gridview in my code. The code which you have suggested uses Gridview.

        For Each col As DataControlField In grid.Columns

   If col.HeaderText.ToLower().Trim() = ColName.ToLower().Trim() Then

                Return grid.Columns.IndexOf(col)

Hi,
I converted the code given by you into VB.Net as I am using VB.Net for my coding
purpose.
The code which I wrote based on your code is as below.
But it is giving me an Error on Line 5;
Error is :
Value of type 'System.Web.UI.WebControls.DataControlField' cannot be converted to 'System.Web.UI.WebControls.DataGridColumn'

Hi,

Please try to use the below function.

private int GetColumnIndex(GridView grid, string ColName)

        {

  foreach (DataControlField col in grid.Columns)

            {

                if (col.HeaderText.ToLower().Trim() == ColName.ToLower().Trim())

                {

return grid.Columns.IndexOf(col);

  }

            }

return -1;

        }

Hope this will help.
