There was an old post about this but I've never been able to find it. At high zoom levels (20 and 21), the Aerial mode usually doesn't show images. Other modes show a zoomed-in version of the previous images, including AerialOnDemand. There doesn't seem to be a way not show labels with AerialOnDemand, unfortunately. Can Aerial be changed so that it also shows the zoomed-in previous images?

Why isn't it possible to set the background to transparent?

It always shows it white or another color you set but not transparent

I am trying to draw a phasor diagram similar to http://www.texample.net/media/tikz/examples/PDF/phasor-diagram.pdf. Basically a polar chart with vectors radiating from the origin based on the magnitude and phase angle between 2 or more signals. A PolarPointSeries is really close but I basically need a drop line to draw the line from the point back to the origin. Changing the symbol at the point to an arrow with the correct orientation would be a nice touch as well.

Hi there,

I have a RadContextMenu on a TreeListView and I've successfully hooked up the context menu to a command in my MVVM view model like this...

... 

          <telerik:RadContextMenu.ItemContainerStyle>
            <Style TargetType="telerik:RadMenuItem" BasedOn="{StaticResource RadMenuItemStyle}" d:DataContext="{d:DesignInstance data:IContextMenuItem}">
              <Setter Property="Command" Value="{Binding Command}"/>

This gets fired on both left clicks on the menu item as well as right clicks on the menu item.  Is it possible to handle right clicks separately?

Thanks

Russell

Hello. I'm new to using Telerik and I'm experiencing strange behavior when editing data in the RadGridView control. I have a GridViewMaskedInputColumn and I lose the first character if I start editing the content of the cell by pressing 2 or more keys in quick succession. I've searched and searched these forums (as well as Telerik's guides and Google), but I could not find anything that helped. Please forgive me if I overlooked something.

My project currently using version 2018.1.122.45 of Telerik's WPF suite. 

Here's a snippet of my XAML, please let me know if more detail is needed. 

Please note that the "Mask" property for the column object doesn't actually contain the ">" sign. It uses the correct notation as demonstrated in Telerik's guide, I just can't figure out how to escape it in this forum. 

Thank you for any assistance. 

Hello, my task is show visible links between appoinments (example in the attachment).

Can you explain me how i can recieve the coordinates of each AppointmentItem?

I can recieve it by VisualTreeHelper, but using this approach i recieve only AppointmentItems which are prepared for drawing (due virtualization).  

Maybe i can use more simple way to recieve the coordinates? Or maybe i can disable virtualization for the RadScheduleView?

Hi

  We get this a Critical Error when we try to move around an event in a RadScheduleView:

System.NotSupportedException: Specified method is not supported.

  Currently we use Telerik version 2018.3.911.45 (Runtime Version V4.0.3.319).

  How can we fix this error?

Thank You,

Hi,

I'm having some problem with the synchronizing the combobox, when ItemsSource updates.

When I select an object and the combobox update, the item is perfectly synchronized with the selected objects value.

My problem is that my application poll new items every 10 sec and update/refresh the itemssource.  I'm using isSynchronizedWithCurrentItem = true and the combobox just set the first item by default, instead of displaying the actual value from the selected object, as before the itemssource updated.

How can I fix this?
