Back button in ajax update panel not working


Back button in ajax update panel not working

To fix the issue you can do History.go(-1) is a javascript function that just redirects to the previous page cached in the browser. There is no round trip to the server, the browser just serves the cached page when it first loaded, so form fields were not preserved since you did an AJAX call on the client. The data did not "POST" in the browser, so that is why you see the fields empty.
You can have your submit button to a postback to the server, and handle the redirection there to get the desired outcome. There you will have ViewState preserved, and can load the previous page with data preserved.

I wish did fix the issue. The solution I found was using a HiddenField besides each Checkbox. The Hiddenfield has the id of each item.
Then I set a Cookie with subkeys, each subkey contains the id of each checkbox checked.

With these it helps Change the UpdatePanel's UpdateMode Property to "Conditional".

hope this fix your issue You can use the ScriptManager to register the control as a postback control. Do something like this in the ItemDataBound event:
Every time button cause full post back, even it is in update panel

Hope this helps I've tried your code in a blank Solution, using Visual Studio 2010, .NET Framework 4.0. Changing the following, I manage to avoid the full postback from the buttons:
I've added the AsyncPostBackTriger property for the Click event for each button and SelectedIndexChanged for the DropDownLists. Also I've configured the UpdatePanel properties ChildrenAsTriggers="false" and UpdateMode="Conditional". Following the same approach for every UpdatePanel will do the trick.
