I tried both of these:

   If tblTable.Rows(0).Cells(0) IsNot Nothing Then
               Dim strstring As String = "something"
   End If


   If tblTable.Rows(0).Cells(0).Text <> "" Then
                Dim strstring As String = "something"
   End If

This is the error message I get:
Specified argument was out of the range of valid values.
Parameter name: index

tblTable is data table?

Please check to make sure that the dataset is not empty.
do this
if (ds ! = nul && ds.tbltable != null && ds.tbltable.count > 0 )

It is a web control (asp.net table).

I found my own solution... will store the values of tblTable in an array then retrieve them later when I need them. It is a small table anyway. An arraylist should do it.
If anybody has a better idea, let me know.   Thanks.

Hi,

Please check code for reading cell values (C#).
