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

The encountered issue stems due to inheritance of CSS rules that select globally table elements. 

For the time being you can use the following CSS reset to improve the layout of the Editor's table elements:

.reLayoutWrapper, .reWrapper_corner, .reWrapper_center,
.reLeftVerticalSide, .reRightVerticalSide,
.reTlbVertical, .reToolCell, .reContentCell,
.reToolZone, .reBottomTable, .reEditorModesCell,
.reBottomZone, .reResizeCell {
	border: 0 none !important;
	padding: 0 !important;
}

.Telerik.reWrapper, .Telerik.RadEditor .reContentCell,
.Telerik.reColorPicker, .Telerik.reInsertTable,
.Telerik.reCustomLinks a:hover {
	border: 1px solid #828282 !important;
}

.reLeftVerticalSide, .reRightVerticalSide {
	padding: 1px !important;
}

Note that these CSS rules will affect RadEditor controls outside the RadGrid. If you need to modify only RadEditors inside RadGrid, use CssClass property and change the CSS selectors according the set class name.

Also, upon the used color you may need to change the border-color according to the Skin design.

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>

Full featured File Download Manager!
Very similar to the AsynchUploadManager, just in the other direction.

 functionality:
  - download multiple files in asynch mode
  - set a limit to the number of simultaneous downloads
  - progress bar/cancel options for each
  - default to client side 'downloads' directory
  - Handle filestreams
  - convert on the fly using document processing {download as PDF}
  - zip on the fly
  - cache temporary files for sending via email as attachments
  - notify on complete per file or per batch

Thanks!

Hi guys,

Do you think that the Telerik UI for ASP.NET AJAX suite should offer a Radial Menu? The control should optimize and facilitate the work on touch devices.

You can find more detail for the control at:

Thank you for your feedback!

In an effort to better promote Client-Side development that leverages your API, I recommend you update your demos that capture and log events (such as http://demos.telerik.com/aspnet-ajax/input/examples/programming/clientside/apievents/defaultcs.aspx) to behave and act more like the Web Developer Console logging of objects (treenode). 

You could put a control together on the page, but I was thinking at the very least you could just add the console.log lines on these demos.. 

Also, I did a page recommendation on one of your documentation pages that covered clients side events on RadTextBox (I believe).. An event capturing demo that doesn't link to Telerik's EventArgs is kind of pointless to me.. but it would seem there isn't much documentaion in this area. So console logging the event args is just about the best way to review them.

As a workaround use the overload method Dock(String zoneID):

RadDock1.Dock(RadDockZone1.ClientID);

Using GIF image in the RadEditor to resize them or manipulate them somehow and saving them, results to a GIF file with black background.

You can safely use PNG images when transparency is needed, which are fully supported.
