Both DataSource and DataSourceID are defined on 'DetailsView1'.

Hi Satya,
Actually I resolved it but I am still trying to figure out what was the cause.
I just created a new aspx page from scratch and re-did my whole code again. I am using oledb connection.
It just worked.

All I can think of i did different was that in my last page i used Control to bind to the source first to get exact connection string. Then I deleted the control and re-did the connection using code behind. May be that cutting and pasting messed up something. I hope I could find what it was..But thankfully its resolved.

Thanks for ur quick response.
