While editing the XAML document, I'm experiencing weird behavior in VS2019. 

All examples applies when the Design editor is active together with XAML editor.

Example 1:

Selecting XAML with mouse stops when i start selecting the telerik:RadComboBox 

Example 2:

Copy Pasting bugs out, either the selection is empty or incorrect !

Example 3:

'Forcus' in Visual Studio is sometimes overtaken by the RadComboBox which is very annoying. 

Hi All! Here is what I'm trying to achieve with the RadNavigationView (RNV):

• Main content is full screen map in the background and through the RNV would toggle different overlays or options.
• Depending on what the selecteditem is, show/hide/resize content area.

What's the best way to achieve that behavior with the RNV?

I created a simple round button by setting Width and Height properties to the same size and CornerRadius to Width/2. Until now this worked perfect in my application.

After updating to R2.2021 (Telerik.UI.for.Wpf.NetCore, 2021.2.511) I noticed that buttons ignore the CornerRadius property when using the Fluent Theme. This was not the behavior in previous releases. 

Steps to reproduce:

1. Create a WPF Core project (.NET Core 3.1)
2. Add Telerik.UI.for.Wpf.NetCore (2021.2.511) via NuGet package manager
3. Modify App.xaml to include all resource dictionaries necessary for Fluent Theme
4. Create a button:

<telerik:RadButton Content="DOH!"
                   Height="100" Width="100"
                   CornerRadius="50" />

The button is just a square, not round. When changing the theme to e. g. VisualStudio 2019 the button is round again. (see attached pictures)

Hi Team,

We have an application in which we are using gauge control to show some values. This application is currently supporting many themes and themes are applied as per the selected theme. But in few of the themes the RadSemicircleNorthGauge display the white background which is make design look bad. We have tried to remove it but did not find any way to do so. Is there any way through which we can remove it so that it will not be shown in any themes. Attaching here with the images showing the same gauge in 2 different theme. 

Kindly help us resolve this issue.

The attached 2 images are visible in respective themes:

1. Image with background - In Crystal Light/Dark, Fluent light/Dark

2. Image without background - In Office2016, Office2016touch, Expression Dark.

I have a LineSeries where I can add new points by clicking on the chart.

Most of the time everything is fine but sometimes the lines are connected to the wrong point.

It only happens when the time values are close to each other.

If I close the page with the chart and open it again the lines are drawn correctly.

1. Is there a way to get the chart to draw the line correct?

2. If not 1. Then can I somehow force a refresh of the chart?

I have a template for a customized control panel for my grid (see below).
It has been working fine for over a year, until I did the latest update (2021 R2).
Now I get an error that the CotrolPanelItemCollection is not part of the RadGridView.

Getting really frustrated lately with updates causing more problems than solutions :/
Right now both Blazor and WPF are unusable

How do I clear the RadMultiColumnComboBox text when the SelectedItem value it is bound to is NULL?  The ComboBox retains the value of the previous selection.

SelectedItem="{Binding SelectedPricedLineItem.ManufacturingGroup, Mode=TwoWay}"
DisplayMemberPath="DisplayValue"

When  SelectedPricedLineItem.ManufacturingGroup is NULL, the value displayed is is from the previous LineItem

Setting SelectedIndex to -1 is not an option since that would break MVVM.

Good morning, I would like to know if there is a tool to move text or any part of the image, it would be very useful. I hope you can answer my question.

best regards

Hello.

I want to customize the header for the tab control.

1.(red) I want to change or delete the color of the underlined line for the selected item.

2(blue). I want to change the mouse hover background color of tab items.

3.(orenge). There is a "+" button after the menu with AdditionalContent. I also want to put a "*" in front of the menu.

Some old data used navigationtabcontrol, so I couldn't find a recent example.

I'd appreciate it if you could tell me how to style each of these.

Thanks.
