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!

..... if you need more information, please ask!

Like mentioning that this is an ASP.NET question? At least, that's what I assume from the word "Gridview" :S

I think you will have more luck in the ASP.NET forum. It doesn't sound like a raw AJAX/Javascript thing.
