Hello all, I'm hoping to get at least a pointer in the right direction here.
Long story short, I've got a DB that I'm displaying information from. I'm doing so using a GridView under a TabContainer / UpdatePanel.
Everything works fine, except one weird point - if you click on a row of displayed data, you get a proper postback, and you are brought to the item's information page.
If I navigate via the menu back to the page containing the TabContainer, all is well.
HOWEVER, if I click on my browser's back button, I get an invalid cast error if I click on another product.
Now, if I click on the tab again (even though I'm already on that tab - I store the tabIndex via a cookie) all works fine.
Any ideas why the back button would cause this behavior? I'm relatively new to this, so if you need more information, please ask!
