Disappear row on IE 11

[Mariusz]

Hello,

I have a problem with show data in locked column on Internet Explorer 11. The problem appear for example when I expand some row or I added new to structure. When I use Chrome or Mozzila treelist behave good. Has anyone idea how fix this problem?

Thanks.

Hi,

Could you confirm that you are using the latest Telerik.UI for ASP.NET AJAX version? If yes, send us the problematic code so we can test it locally and advice you further.

Yes, I'm using the latest version 2015 Q1 (2015.1.429) but kendo ui (sorry for my mistake). Have I create new topic in kendo ui topic?

I've noticed another problem, in version 2014 Q3 combobox doesn't scroll top after read new data, in version 2015 Q1 always after read scroll is on top. I need the same solution  in version 2015 Q1 as this (topic from forum ).

Hello,

Yes, it would be better to create new ticket for Kendo UI.
