When the DirectX D3DImage reports its front buffer is available for drawing and that said image is not displayed inside the webcam control an exception is thrown.

It would be really great if the autocomplete box could handle the page up/down key to skip multiple entries at once. As we have like 200 entries in the list it would be a great advancement for the users using the keyboard.

Already tried your example from the forum but it is not functional.

All the best!

When creating a NetCore project with NoXaml binaries via Telerik VSExtenstions for WPF and the installation of UI for WPF suite is not on C drive the following error occurs: "Error occurred while restoring NuGet packages: The local source 'C:\Program Files (x86)\Progress\Telerik UI for WPF R2 2020\ToolboxNugetPackages\' doesn't exist."

 

Providing similar to the traditional Windows Forms Multiple Document Interface (MDI) features.

As we now have support for Webcams with RadWebcam-Control how about supporting Twain? But not the old version, instead the platform independent newer Twain-Direct. There is already C# Source Code under MIT-License available: https://github.com/twain/twain-direct. I think this could be used in Xamarin and WinForms, even ASP.NET also...

It would be awesome if the user would be able to create folders for visual organization in tree views, tree list views and list views. These folders should not be actual items in the tree, but rather be a visual simplification for complex lists and trees.

Folder specific features:

• Add, move, rename and delete folders
• Add or move items to the folders (for example via drag&drop)
• Move and delete folders with their content
• Verification, if certain types are allowed in a folder
• Sort the content of the folder

  View specific features

• Switch between “folder view” and “folderless view”
• Save and load structures, similar to the LayoutControl
• Verification, if a folder is allowed to be moved to or created in certain areas
• Possibility to manipulate the structure from the code

With this feature the user would find it easier to organize sometimes complex trees and lists into manageable folder structures, as the layout would be created by the user himself. The folders also make collective operations on items in them easier to handle, as the user can move or delete the folder with its content and does not need to select long lists of items for every operation. This would increase the usability of the trees and lists.

Hello,

We want to integrate a web browser in a flyout pane in WPF to display html 5 pages. Moreover, we want to display some html contents in tooltips too.

The provided WebBrowser by WPF framework does not work well.

Consequently, the idea is to have a "htmlplaceholder" (as you provide in silverlight) which supports HTML 5 and could be based on chromium engine.

Thanks & regards,

 

When a RadGridView column is bound to a sub-property e.g. "Player.FirstName", one can cancel the edit operation while the value of the cell's editor is invalid and the original value is not restored.

We can help our customers to achieve a different look of their applications by setting a custom palette.

Exception when editing the template and showing the tooltip of the ValidationErrorElement 

Workaround:

Replace the validation element: 

<Grid x:Name="ValidationErrorElement" Visibility="Collapsed">
    <Grid.ToolTip>
        <ToolTip x:Name="PART_ToolTip" Placement="Right" DataContext="{Binding RelativeSource={RelativeSource TemplatedParent}}">

Testing in the RadColorEditor control:
   looking the attachments,Select the two numbers on the left(the file "Select.png"),
then enter a number through the keyboard,just modified the number on the far left(the file "Input1.png").
But sometimes the two numbers that are selected are replaced,like the file "Input2.png".
Obviously the second case input experience is better!
Continuous restarts cause one of the two.

NuGet: A wrong dependency is added when installing the SpreadsheetStreamingExport package.

Hi All,

I would like to hide the mouse over background to TreeListViewRow, and now the solution that I know is to edit the template my self.

Is it possible to add custom value for MouseOverBackground, SelectedBackground like GridViewRowStyle?

 

Thanks in advance for you feedback.

The image quality is changed when pasting an image. 

look the attachment,when move the float window over the top Compass,and just there is a document tab under the Compass,
the place preview will flash.

In the Crystal theme the ScrollBars are narrow and expand their size when the mouse is over. Introduce property that sets the default appearance of ScrollViewer's ScrollBars, similar to the ScrollBarMode property for the Fluent theme, which has the following options for the ScrollBar size:

• Auto - narrow & expands to normal size
• Compact - always narrow
• Normal - always normal size
