Try this

C#

protected void gvSdt_SelectedIndexChanged(object sender, EventArgs e)
{
       GridView gv = sender as GridView;
       if (!Equals(gv, null))
       {
           int rowIndex = gv.SelectedIndex;
           string strValue = gv.DataKeys[rowIndex].Value.ToString();
           // Do your stuff here
       }
       else
       {
           // Generate error message here
       }
}
