No Solution ???????????

[leela mn]

sorry for the delay
I just did minor changes in your code
and its working fine....
change the postbackurl of the image button to this

PostBackUrl='<%#"~/Admin/brochureAdd.aspx?Bid=" + Databinder.Eval(Container.DataItem,"vchBrochureId") %>'

and let me know if this works fine........... ...
