RadListBox How to change check item to uncheck item

[JEONG]

I used two RadListBox, one is right and other left on screen.

And Explorer apply Compatibility View Settings.

So Explorer Version is IE5, but I didn't have any problems.

before upgrade telerik Version.

 

I used to use 2014.2.724.35 version. And now upgrade to 2016.1.225.35

And then RadListBox got a problem.

When I scrolls down and select a item. (on name)

Immediately ListBox scrolls up and uncheck that item.

 

If I select a item (right side name), I can check it but can't get back uncheck item...

I try to select a check item, automatically scrolls up again......

 

I think that is Version problem but I have to use IE5 and apply Compatibility View Settings.

How to figure out this problem...

 

 

Please answer

Hi,

I am afraid that as of 2015 Q3 the lowest version of Internet Explorer supported by Telerik UI for ASP.NET AJAX is IE 8, as noted on our Browser Support page. And at the time your previous version was released, the lowest version of Internet Explorer supported was IE 7. If you have not encountered any issues before using IE 5, it has been an exception, rather than an expected behavior.

Feel free to contact us again, if you have any questions.
