Rebind after Empty List<T> binding Does not Update RadListView

[Kris Ivanov]

Here is the scenario:

1. Create a RadListView as per the documentation
2. Call Rebind where the NeedDataSource uses List<T> with 0 records to set DataSource
3. RadListView shows correctly 0 items
2. Call Rebind again where the NeedDataSource uses List<T> with 3 (or any > than 0) records to set DataSource
3. RadListView shows incorrectly 0 items

If I switch between any number of records larger than 0 it works fine. As soon as I use 0 record collection for DataSource it does not matter what collection I rebind to it shows none after that.

What is the problem?

I was having the same issue last week. I tried the hotfix and it works.

[Matt Bell]

I am having the same problem and am new to these forums.  Could you let me know where you got the Telerik.Web.UI_2009_3_1121_hotfix from please?

Hi Matt,

The fix should be included in the 2009.3.1314 version of RadControls for ASP.NET AJAX (Q3 2009 SP2) which is available for download from your account on telerik.com. Upgrade instructions are available here.

Thanks for the fast response Sebastian.  Silly me - I had the latest version in my development environment but for some reason had an old version on the live system.  It works a treat now.

[Richard Maly]

I think I am experiencing the same problem but with version 2010.1.519.35, is this possible?

[Rosen]

Hello Richard,

I'm afraid that I'm unable to recreate the described behavior with mentioned by you version (or later) of RadControls for ASP.NET AJAX.

Thanks for your quick response,  and you where correct it was my bad.  My Rebind() was not being called. 

needed to step away from the problem for a couple of days :-)

Hi DJINGAREY,

As I mentioned previously, try to migrate to the Q3 2009 SP2 release of RadControls for ASP.NET AJAX (2009.3.1314), following the instructions from here, to see whether this helps.

I folow instruction but in my download account, i can't find ASP.NET AJAX (2009.3.1314).
In my download section i have got only RadControls for ASP.NET AJAX Latest Version: 2009.2 826 (Aug 26, 2009)

[Sebastian]

Hi DJINGAREY,

I checked your account and it indicates that you own AJAX Single Developer without subscription license for our Q2 2009 release. If you would like to receive the Q3 2009 SP2 version or better yet the latest Q2 2010 SP2 release of the suite, you will need to perform an upgrade. Your options are listed here - for additional inquiries you can contact our sales team directly at [e-mail].
