Question

I am using the GridView - AutoGenerateSelectButton = \"True\" to select the row in order to get the Column 1 cell value.

I have tried:

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 > 0)
        {
            if (gvGrid.SelectedRow != null)
            {
                GridViewRow row = gvGrid.SelectedRow;
                int iCol = gvGetColumn(gvGrid, sHeaderText);
                if (iCol > -1)
                    sRetVal = row.Cells[iCol].Text;
            }
        }
        return sRetVal;
    }

    private static int gvGetColumn(GridView gvGrid, string sHeaderText)
    {
        int iRetVal = -1;
        for (int i = 0; i < gvGrid.Columns.Count; i++)
        {
            if (gvGrid.Columns[i].HeaderText.ToLower().Trim() == sHeaderText.ToLower().Trim())
            {
                iRetVal = i;
            }
        }
        return iRetVal;
    }
}
