You need to support touch capabilities in your ASP.Net controls. Drag and drop and swiping are critical to my apps that I build for the PC. With Windows 8 and touch screen monitors now prevalent, you need to support them!

It seems however that the problem comes from the unusual CSS style selector that you use to set the width of the RadTextBox controls. Based on the information of this help article, you should correct your CSS rule like this:

Copy Code
.three_column .RadInput
{
   width: 448px !important;
}

Note the missing .riTextBox class from the selector. You should not apply width for the inner input element (which this selector controls), but only to the outer wrapping span element controlled by the .RadInput class. After applying this change on my side, the problem didn't reproduce any more.

Yet another approach to fix the issue is to use the inline Width property. However, based on your code I suspect that you intent to change the width by CSS rules and that is why I would recommend the modification in the code block above. 

When a RadEditor or SPRadEditor in a custom WebPart for SharePoint 2013 is placed in an UpdatePanel or RadAjaxPanel it is not ajaxified and loses its content after a post back.

I am not having success on having wrap="false" for my RadGrid. The solution:

(e.Column as GridBoundColumn).DataFormatString = "<nobr>{0}</nobr>";

Will not work since I have hover over and links on several of my columns.

Couldn't RadGrid have a setting of wrap="false" that would apply to the entire grid?

Like control ProgressBar in WinForms.

(I didn't find RadNumericTextBox in the category)
Telerik version - 2011.1.614.35

Auto complete box floats at a distant place, away from the RadNumericTextBox.
i.  The auto complete of IE 9 is on, enter some number, save the form.
ii.  Again open the form, focus on the numeric text box. The auto complete box seen is  not aligned with the control.

Based on customer feedback:

I put a DrowDownTree, then I put another textbox under DrowDownTree. If I expand the item of DrowDownTree, I found some item will be shut out by textbox.

Only happens in _pure_ IE6

In pure IE6 the DropDownAutoWidth does not work as expected e.g. the dropdown gets too wide.

Update the Http handler shown in the following forum thread so that it can be used with the latest version of Telerik UI for ASP.NET AJAX:

If I create a table and add some content to one of the cells, when I click on the content and click either the ordered or unordered list buttons, the <td> tag gets replaced the the <ul> or <ol> tag.

I was able to replicate this on all browsers I tried using the demo at http://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx
