Hi Saravanan,

You may change the negative quantity to N/A and color it in the
DataGrid.ItemDataBound. The following is a code snippet for demonstration.
You can modify it to meet your requirements.

private void DataGrid1_ItemDataBound(object sender,
System.Web.UI.WebControls.DataGridItemEventArgs e)
{
if(e.Item.ItemType == ListItemType.Item
||e.Item.ItemType==ListItemType.AlternatingItem)
{
Label l=new Label ();
l.Text ="N/A";
l.ForeColor =Color.Red;
if (Convert.ToInt32 (e.Item .Cells[3].Text)<0)e.Item
.Cells[3].Controls.Add(l);
}
}

Does this answer your question? Please let me know if you need more
information

Best regards,
Lewis

In DataGrid_ItemDataBound(...)
Dim lbl as Label
lbl = CType(e.Item.Cells(0).Controls(1), Label)
If Val(lbl.Text) < 0 Then
lbl.Text = "N/A"
e.Item.Cells(0).BackColor = Color.Red
End If

The Label, when rendered, is enclosed in a literal - so Cells(0).Controls(0)
will not get your control, Cells(0).Controls(1) will be your control. In the
example above, i dim a label & cast the contents of Cell 0 Control 1 to it.
