When the control is modal it should create a second iframe behind the modal background like it creates one behind the popup itself. This will allow the modal background to stay above heavy-weight objects in IE as well.

The control will provide the ability to hover over an image and zoom-in the selected part in a previewer. Such control is available in Google Maps as shown in the attached screenshot Overview-Image-Map-Control.png. Yet another example is displayed in the second screenshot.

You can comment and share your examples or features you would like this control to support.

When large zip files with a lot of files inside is uploaded, the httphandler throws an System.OverflowException "Value was either too large or too small for an Int32." This only happens in HTML 5 File API mode.

The sprite images for the RadButton are moved from the "Button" folder to the "Common" folder of the skins, but the Visual Style Builder searches the images in the Button folder.

The workaround is to extract the archive generated by the Visual Style Builder, move the sprites from the Common folder to the Button folder, archive the files again and import them in the Visual Style Builder. This allows you to edit them in the tool and after that you can download the skin and move the sprites back to the Common folder.

My ASP.NET project updated 2013 Q1.

Not bad. but I found some error.

RadGrid's clientSettings element of AllowScroll = 'true' if the layout is broken.

The reason for the scroll function will render the data area is divided into a new DIV.

HEADER column portion and a data portion, while the size of the column is divided 

into different DIV does not fit.

Attach the file. Look the screenshot.

When i copy paste bulleted conted from MS word 2010 in Rad editor, it appends extra style margin in the last line and shifts the content towards the right. I  used StripFormattingOptions= "MSWord" and StripFormattingOptions= "None SuppressCleanMessage" but none of these options are helping.
I also disabled all the filters. Please let me know how i can retain my bulleted formattings while i copy paste from MS word 2010.Attaching the screenshots

formatting is lost when content is pasted from ms word 2010 to radeditor

Add the ability to have scale breaks in the RadHtmlChart.

Since there are still several customers that need support for old browsers, why not create two separate sets of controls.  The existing ASP.Net Ajax controls maintain support for old browsers while HTML5 Ajax controls are not.  Personally, I do not need support for old browsers and would like to see leaner, better controls built from the ground up just to support HTML5.

I just had a chance to use RadColorPicker in the RadGrid. after having few discussions with Andrey, it seems like to use it in edit mode and be able to bind back, it requires a lot of coding in the code behind and converting rgb to the right format. The code does not look complicated. I propose to add something like <telerik:GridColorPickerColumn that similar to <telerik:GridAttachmentColumn and <telerik:GridHTMLEditorColumn so users can just drag and drop easily. This should be beneficial to anyone who use the control.

I have a RadToolbarDrorDown that allows users to select a different theme. This works fine in Firefox and Chrome, but the dropdown fails to show in IE (v10). It does appear to work with IE 9.0.8 however.

In IE 10 I see this script error in the console:

	SCRIPT5007: Unable to get property 'documentElement' of undefined or null reference 
	ScriptResource.axd, line 147 character 2

Also, the html generated is quite different : see attached

I'm using a gridview that used to work before I installed a new trial version (the old one did expire in the middle of our evaluation). The gridview code is taken from your example i.e. I haven't added any extra functionality it's all out-of-the-box. All I did was to connect to our SQL server datasource. The component that errors was already there from the beginning.

The multiline textbox should increase its high while the user types, after the currently available space if fulfilled. Like in Facebook "What's on your mind " textbox  

When 'Track Changes' functionality is enabled and a text in RadEditor is deleted via Backspace keyboard button while the page is viewed under Chrome or Firefox, the cursor is positioned after the selection, while the expected behavior is to place it before the selection.
