 var result = (from f in dtCloned.AsEnumerable()
                      group f by f.Field<string>("AssetDescription") into g
                      select
                      new
                      {
                          AssetDescription = g.Key,
                          TotalAmount = g.Sum(r => r.Field<double?>("Amount"))
                      });
foreach (var aAsset in result.AsEnumerable())
{
  if (aAsset.TotalAmount < 0)
  {
     foreach (GridViewRow arow in GridProjectDetails.Rows)
     {
         string AssetDescription = ((TextBox)arow.FindControl("TextAssetDescription")).Text;

Hi Ashish,

I got the output by removing the existing (default) css class and adding this css class with textbox. it worked.

Here is the complete code

protected void btnSubmit_Click(object sender, EventArgs e)
    {
        ValidateAmount();
    }
    private void ValidateAmount()
    {
        System.Data.DataTable dtGridData = new DataTable();
        DataTable dtCloned = new DataTable();
