As far as I know, there are no way to set the color of the title bar. As far as I know there are no properties "color" of the title bar.

Thanks 

I've downloaded the latest Sample Application for Terlerik UI for WPF R1 2021 SP1

When I try to select the RibbonView sample I get a MessageBox with message "Exception has been thrown by the target of an incovation" and the sample does not load.  All other samples work fine.

Good afternoon,

When we add a new child element to the RadDiagram(see attach file), the diagram automatically optimizes their layout. After the chart is updated, the new element and its parent are automatically moved to the left side. How to make them stay in their places?

There is a small discussion of this problem on the forum.

We use a RadTileList as our main navigation component. Today we noticed that our app's memory consumption only ever increases when opening modules and never decreases when closing them. When tracing memory usage with DotMemory (using the Key retention paths feature), I noticed that the retention path to the leaked module viewmodels seems to be rooted in the RadTileList component (see the attached screen shot).

A few implementation details:

- We are wrapping our modules in a class called "OpenedModule" (as you might guess from the attached image)

- The RadTileList is databound to an ObservableCollection<OpenedModule> via its ItemsSource

- We do not use grouping

- Closing a module results in the module's "OpenedModule" instance being removed from the ObservableCollection

This is the xaml we use to instantiate the TileList:

<telerik:RadTileList 
    x:Name="NavigationRadTileList"
    ItemsSource="{Binding OpenedModules, Mode=OneWay}" 
    CanUserSelect="False"
    TilePlaceHolderSide="90"
    behaviors:DisableTileListRightClickBehavior.IsEnabled="True"
    ItemTemplate="{StaticResource NavigationTileListTemplate}">
    <telerik:RadTileList.Resources>
         <Style TargetType="{x:Type telerik:Tile}" BasedOn="{StaticResource NavigationTileStyle}" />
    </telerik:RadTileList.Resources>
</telerik:RadTileList>

Judging by the result from dotMemory, it looks like the TileGroup's children are somehow cached in an ordered list which is not updated when an item is removed?

Issue : Currently the Free Trial / Download page states "Over 120 UI controls" yet the product pages states "over 140".

Obviously "Over 120" is technically correct, however, 140 is more accurate, sounds better & increases consistency across the site.

The same issue also applies to the "UI for WinForms" description and its respective product page.

At this time, Telerik UI for WPF distributes libraries build for each TFM -> WPF45, NetCore and NET50.

If there was a way that UI for WPF could compile some of those libraries .NET Standard 2.0 compatible, it would allow for the developers making the transition from .NET Framework to .NET Core/.NET5 a but easier because they will be able to share the reusable Telerik code in a class library consumed by both WPF45 and WFP50 projects

Sometimes RadVirtualGrid.ScrollRowIndexIntoViewAsync throws NullReferenceException.

Inside RadVirtualGrid.ScrollRowIndexIntoViewAsync the following method invoked:

this.MainPanel.ScrollRowIndexIntoViewInternal and this.MainPanel is Null, since RadVirtualGrid.Refresh() that was called previously makes MainPanel Null.

The Refresh method is public, so could be called anytime by mistake or not.

So, please fix one of those or even maybe both:

Refresh should not set MainPanel to Null.

Inside RadVirtualGrid.ScrollRowIndexIntoViewAsync check that this.MainPanel is not Null like you perform this check in most RadVirtualGrid methods.

Thank you in advance.

I would request a new control. The RadButtonTextBox like the one in WinForms.

For fields with for example phonenumbers or emails we could then add a Button for launching the SIP oder Emailclient.

The possibilities are endless. Look at the "TextBox" in your browser window ;)

It would be very useful for us if the RadWebCam control (WPF or WinForm) could support ONVIF Profile S

Thanks

When the FluentPalette.Palette.ScrollBarsMode property is set to Normal, the ScrollViewer scrollbars overlap the content area. This should not happen.

To resolve this, set the ThemeHelper.ScrollBarsMode attached property of the ScrollViewer controls using an implicit style.

<Window.Resources>
	<Style TargetType="ScrollViewer">
		<Setter Property="helpers:ThemeHelper.ScrollBarsMode" Value="{telerik:FluentResource ResourceKey=ScrollBarsMode}"/>
	</Style>
</Window.Resources>
