Today we have released Service Pack 1 for Q2 2014 of Telerik UI for ASP.NET AJAX. Let me highlight the most important fixes and new features in the controls:

Critical Issues Fixed


  • The "Undo" button is not working when ToolProviderID is set
  • When the "AddComment" property is set to true and the content area contains only text, the unselected content is removed in Internet Explorer 9 and 10.
  • The page scrolls when the user pastes in the RadEditor content area under Chrome and Opera
  • The selected element is lost when a dialog is opened in RibbonBar toolbar mode under IE10 and below.
  • When an image in anchor HTML element is replaced via the Image Manager, the anchor is removed.


  • When the EditMode is set to Batch and the user tries to open a cell/row for edit, a JavaScript error is thrown in IE7 and IE8.


  • The single click of RadButton gets disabled permanently if а required field validator error is detected.

RadGauge & RadHtmlChart

  • The controls are not rendered in IE 11 with Document Mode 7 or 8.


  • The hovered items of RadRating when Precision=Item remain in hovered state when the cursor leaves the boundaries of the control.


  • The client-side events ClientMouseOver and ClientMouseOut of RadRotator are not working.


  • Closing a RadWindow that has either AutoSize and Animations or AutoSize and DestroyOnClose enabled by registering a script from the server in the content page, causes a JavaScript error.

New Features Added


  • Added a HighlightFirstMatch feature for the RadAutoCompleteBox.
  • Improved performance of the control during initialization.


  • Support for all Skins in the Telerik UI for ASP.NET AJAX suite. Here is how the Telerik skin looks like:

    You can examine the different skins through the skin chooser control placed in the top right corner of the demos.
  • Ability to define custom task properties through inheritance.


  • Improved RadGrid load time in debug mode when there are a lot of hidden columns.


  • Introduced WCF WebService support for RadToolTipManager.

You can find a detailed list of all fixes and improvements in the Release Notes.
