Hi Sanjeev,

Great solution.

Just wondering that how do we access the values present in the user control loaded this way?

Lets say - you added 5 user controls which have got 2 textboxes each. Now you want to save all the values present in these 10 textboxes. How do we do that?

Please help :)

Thanks - Ishan

Thanks for wonderful piece of code. But this is not useful if you want to do any server-side execution in the user control.

I've just found something out that may help some people.

If you don't need postbacks from the dynamically loaded control you can just remove the second __VIEWSTATE field from the dom using jQuery with this line...

$("input[@name='__VIEWSTATE']:eq(1)").remove();

Put this in your ajax success function after the new html has been added to the target div and it will stop the error happening.

I tried to merge the 2 viewstates using jQuery but it still broke.

Hi Sanj

How do you merge viewstates mate? I can't find anything on the web about this.

Cheers

The state information is invalid for this page and might be corrupted

Hey great article.

I took your base code and extended it slightly into a tabs example. I also removed the controls viewstate entirely to fix the corrupt viewstate errors I was experiencing on postback.
