To whom it may concern,

In our MVVM-project, we are using a derived implementation of the RadRibbonWindow to add some customized functions, for example to add EventHandlers firing when something changed in the view, for example language or culture setting changes from another window. With the EventToCommandBehavior binding, we would like to pass the fired custom event to our view model to execute an async command. Although the event is not shown for autocompletion, everything works fine during runtime, and the command is executed when the event was fired. Unfortunately, the VisualStudio XAML designer cannot bind the custom event handler for the EventToCommand Behavior tag and therefore shows an exception within the XAML code, and within the XAML designer. Because of that binding problem, we are unable to further use the designer to get a preview of our designed windows.

We tried to derive our window from the basic WPF window (System.Windows.Window) and simply add the custom event handler but it did not work, either. Is there any problem with our implementation, or with the EventToCommandBehavior leading to an exception during design time? I have attached a minimal working example. In the code, I have derived a customized window class from the basic WPF window (shows the same error as the RadRibbonWindow), and have added a new event handler. This window is used as main window and fires the custom event when the event OnContentRendered function is called. The view binds this event within XAML to a command of the view model. The command is implemented with our customized asynchronous command. The XAML designer throws the described exception (as shown in the provided picture) but when I debug the program, a break point set within the function called by the command is hit.

I have removed the package "Telerik.Windows.Controls.for.Wpf.Xaml.2021.3.1109" within the .zip-folder because the code would have exceeded the maximum file size.

Sincerely,

Matthias Jörg

We are using RadRichText box along with HtmlDataProvider to create new para in specific notes- comments. As our application heavily relay on adding comments in html format when adding/ forwarding application to another user.

As a main control RadRichText box is working fine and dev team is recommending to use it in Production. But issue happens when we are rendering all comments as list associated to one application. Currently we have some application having more than 200 comments.

We used RadRichtext box to render HTML as readonly. but I impacted performance. Page take enough time to load contents. 

Currently we replaced RadRichText box with HtmlRenderer.WPF (HtmlPanel) control, which is much efficient compare to Telerik control. However HtmlPanel has its own limitation.

I wish if Telerik has such lightweight control to render HTML content in more efficient way, which does not effect application performance.

Hello!

I'm in need for a VisibleColumnCount dependency property for RadGridView (or GridViewDataControl I guess).

Just like FrozenColumnCount actually, so I guess this is just a simple dev but I can be wrong?

It would be so helpful, because I have a textbox ("search column with name") that I use to toggle the visibility of the columns in my RadGridView, and I want to do stuff whether there are matching columns (like, displaying a text "No results").

Currently, I'm using a bunch of converters to do the job an it leads to quite ugly and hard-to-maintain code.

Thanks in advance!

Arthur

We distribute two types of themes solutions with our source code. The first one are: Themes.Sources.sln (for Silverlight), Themes.Sources_WPF.sln and Themes.Sources_NetCore.sln which are used to rebuild our themes. The second one are those without Source in their names, which are used to distribute the output files. Adding references there will remove the errors which appear.

Currently RadComboBox has no property to prevent user from clearing it with backspace. Also ComboBox SelectedIndex may become -1 when ItemSource is changed.

New propery (CanClear) could be checked on KeyDown event, when item collection is changed or when SelectedItem is changed..

If CanClear is set to false:

Backspace is ignored on KeyDown.

If collection is changed and collection size is greater than 0, ComboBox SelectedIndex becomes 0 automatically.

If SelectedItem becomes null and item collection size is greater than 0, ComboBox attemts to select first non-null item from collection.

Currently, all named sets are placed in a folder named "Sets". The metadata we query from the server contains names for these folders and we should use them.

I really liked this feature and noticed you implemented it for WinForms already: TextBox Improvements in Telerik UI for WinForms

Would be great to have it for WPF as well!

Add a control that allows you to define a number of steps. Each step should be displayed with some kind of visual (like an ellipse for example) and each visual should be connected with a line. The line could be animated to look like a progress bar.

This kind of visualization is found in the Multi-Step Form feature of Kendo UI for Angular.

In the meantime, you can achieve this effect by implementing a custom control as shown in the First Look demo of RadButtons.

Release LIB 2021.3.1220 (20 Dec 2021)

Using the Color Theme Generator application and applying a custom palette for the Windows8 theme, more specifically any of the dark themes, the RadTabControl's tab foreground colors are incorrect. Specifically, they'll be showing as dark text on a dark background - but the foreground text should be light (not dark). Restarting the Color Theme Generator application with this dark color palette as the default, you'd see the problem disappear - until you switch to a light palette (at which point you have the reverse problem).

Clearing and re-merging the theme ResourceDictionaries solves it.

Release LIB 2021.3.1129 (29 Nov 2021)

Hi,

we recently found that our software crashes as soon as we include a RadAutoCompleteBox in the content of a RadTabControl.

A repro project is attached to this report.

How to reproduce:

  • Add a RadAutoCompleteBox to the ContentTemplate of a RadTabControl and bind its ItemsSource to any collection (the project is set up accordingly).
  • Run the application
  • Change the active tab twice. The first click should work, the second click should crash the application without any user code in the stack trace.

You will get a stack trace similar to the one below.

 

Best regards

Right now, it is not easy to disable styles for standard controls like Button.
Especially when using NoXaml.

You have to create an Empty style on Application level for the control to "rewind" its style.
I do believe this kind of style drags down performance of controls when unloading, since it causes StyleChanged events.

 

Some explanation about performance (how things work to my understanding). Might be BS, but I spend a few hours debugging through .net code to get this idea:

Issue is, that when control is unloaded, its not part of the logical / visual tree of the application anymore, so it falls back to styles defined on assembly level.
e.g. Themes/Generic.xaml.  So the empty styles defined on Application level do not count anymore, but the ones you defined in your theme.
This can be observed on RadTabbedWindow. When unloading pages (like switching between them), controls fall back to the styles defined in the theme from Telerik.Windows.Controls.Navigation, because they are still children of that page.
You can observe this behaviour if you set a Breakpoint in FrameworkElement.OnStyleChanged before unloading a control tree.

 

 

If you'd remove the System.Windows.xaml from your theme-dictionaries so that one can decide to merge those styles or not, that would be great.

Hi

I would like to know if Progress Telerik has some plan to port their WPF controls to Avalonia (avaloniaui.net).

 

Thanks

Laurent

https://www.telerik.com/forums/bug-maybe-xdg0047-error-the-following-type-was-expected-ifilteringcontrol

I've just updated Telerik and are now getting this compile time error:

Severity Code Description Project File Line Suppression State
Error XDG0047 The specified value cannot be assigned. The following type was expected: "IFilteringControl". Modelkatalog.Client C:\develop\data-tool-modelkatalog\Modelkatalog.Client\Controls\List\CarVariantsList.xaml 1

I'm getting this error from 2 XAML documents that both implement a custom Fitler for the RadGridView 

I didn't get this error before, and I'm still able to compile and run the project - which kind of defeat the purpose of [Severity: Error]

Create a SlideView control like the one in the Telerik UWP suite.
https://docs.telerik.com/devtools/xamarin/controls/slideview/slideview-getting-started

The control should  have a content area, previous and next buttons, and dots indicator below, that indicates the currently selected page.

Currently, the digitally signed assemblies are distributed only as a .zip file containing the dlls. Introduce nuget packages for them.

Currently the palette of a theme can only be set for the entire application. Setting the palette per control instance should also be possible.
