Provide an option for the RadComboBox to have as its popup a multi-column GridView together with a further option to search within that popup GridView.

When the custom map tiles provider returns the tiles up to the certain zoom level and the user zooms the map to the level above the supported level then the map should use available tiles from previous zoom level, but it show gray patches instead. It occurs when the custom map tiles provider returns null for unavailable tiles.

It could be an extension to the already available Persistence-Control or a complete Component of its own.

There are OneDrive, Dropbox, GoogleDrive, Amazon Clouddrive, to just name a few and there are many more. In germany there are HiDrive, Telekom Mediacenter, web.de-drive. You can find more on http://www.cloudsider.com/cloud-speicher.

It should provide methods to enumerate, upload and download files, create folders, maybe to download previews of files and file properties.

Such a component would make a perfect fit to extend your great Richtextbox, Diagram and Spreadsheet Controls!

So you could help many developers. But it should not depend on service like Teleriks everlive. 

When you place items in the gallery there are scenarios where the tooltip of the scroll up/down buttons is not correct.

Available in LIB version: 2014.3.1402

When user opens the mini map and changes the zoom level of the map then the MapShapeData objects in VisualizationLayer jump and aren't positioned to correct location. This effect is kept even when the user closes mini map.

This exception could be thrown once in a while when the layer is unloaded.

Based on your new radZIPLibrary it would be great if you could implement a universal, mvvm compatible backup library.

It should provide support for multiple spanning medias, catalogs, discarding old backups after some time, encryption and backup of file ACL and registry data.

This would be a perfect addon for your Diagram, Spredsheet and RichText libraries!

In some cases the ZipArchive requires to use the Flush method for its stream. When the stream like the MS.Internal.InternalMemoryStream does not support it then it causes the NotSupportedException.

I think this could help sometimes to get up to speed, if you could provide XAML code snippets for your controls!

Hello.
Im trying to make a choice between these 3 companies, and Syncfusion salesman has provided me with a line-by-line comparison of the available controls and its feautures for Syncfusion, Telerik and DevExpress. Could you please do the same?
Im interested in WPF controls
Thank you

Telerik separator style overrides default appearance of separators that are not children of StatusBar 

When operation stream is created on top of the stream which doesn't support seeking the NullReferenceException is thrown from the constructor. There are other things which makes impossible using of the ZIP library on the stream which doesn't support seeking. We should fix these things.

Issues:

In some themes, when the element (both TextBox and PasswordBox) is focused, the hover does not appear anymore 

Those two issue should be resolved:

1. Different left padding in all themes (WPF)

2. Different height in all themes (WPF)

Similar to the Windows8 RadRadialMenu

RadRadialMenu is available in Q3 2014.

The DropDownPlacement for the RadContextMenu is placing the drop down on the wrong side (Left places it on the right side) and (Right places it on the left side), the default Auto places it on the left side, annoyingly.  Top and Bottom work correctly.

Check out the visualization at https://github.com/mbostock/d3/wiki/Gallery

It would be great if you could incorporate

PasswordBox: Content cannot be selected and cursor is missing-Windows8 theme

A Telerik.Windows.Analytics.TraceMonitor.Initialize(application, iAnalyticsMonitor) method should be added to Telerik.Windows.Analytics.TraceMonitor class.
