Hello,
I am not able to see any records in GridView2. GridView2 is not shown.
I tried to print record count of datatable and it shows there is
records but nothing is shown in gridview2.
First I try to list products table in gridview1
I have added one column which shows select with hyperlink
When I click on select It adds that row from Products table to
datatable dt
for gridview1 GridView1_Selec tedIndexChanged event is written.
dt is stored in session
Can anybody please guide me what is wrong.
Windows XP
Visual Web Developer 2005
SQL Server 2000 (northwind db)
Thanks
