Creating a complex list nesting, sometime includes creating empty parent list item to include entire sub lists. In Chrome, Firefox and Opera pressing backspace in such items causes incorrect behavior and formatting.

This is actually a browser behavior, and it stems from the deletion of the BR tag inside the parent lists. Under IE, this is handled by native DOM operation that removes the entire parent list item and attaching its sub child's to the previous available one.

Under IE10 and 11 the CrossFade animation causes a random flickering. 

The issue with incorrectly counted header elements comes due to the reason that the main table considers the TH elements as child elements no matter if they are nested in a second table.

You can find attached a simple project with the fixed AccessibleTable dialog set as external.

In IE the command works fine.

In FF the command is always disabled.

In Chrome is always enabled, but using it do not affect the content.

If you need this tool to be always disabled under Chrome, you can use the following approach to disable the tool:

<telerik:RadEditor runat="server" ID="RadEditor1" OnClientSelectionChange="OnClientSelectionChange">
</telerik:RadEditor>

<script type="text/javascript">
	function OnClientSelectionChange(sender, args) {
		if ($telerik.isChrome) {
			setTimeout(function () {
				sender.get_toolAdapter().getToolByName("AbsolutePosition").set_enabled(false);
			},0)
		}
	}
</script>

System.Exception: 453.6 is not a valid value for Int32.

We are currently using v2010 of telerik.web.ui dll in our production environments and planning to move to 2015 very soon. Upon updating in our staging environments we are seeing a massive difference in dll size between the 2 versions. Also the webresource.axd(javascript) in the new version is 1.14MB in size which may cause some performance issues. My question is:

1. Is there a way to reduce this size or do per-need basis loading?
2. Can we refer telerik js files in our master page so that they are not loaded all the time? If so, please let us know how.

We're using Telerik.ReportViewer.WebForms.ReportViewer for exporting to another files format but only exported to excel file I got error message below.

please help to advise for this error.

For the time being you can safely use the same scenario with ContentAreaMode set to Div.

Please add "bootstrap" to drop down list of available skins to base a NEW skin on from style builder. I wish to make some color changes (blue to red) but require all the css and image files.

Thanks.
