Hello,

When using 3 RadRibbonButton of Medium size in the Fluent theme, they are displayed in 2 rows: the first row contains 2 buttons and the second one the last button.

With the Office2013, up to three medium buttons are displayed in a column.

I've tried to add RadCollapsiblePanel.SmallButtonsPerColumn="3" on the RadRibbonView definition, but it doesn't change anything.

I there a possibility to have 3 rows for the buttons in this theme?

I have a RadGridView with RowDetailsVisibilityMode set to "VisibleWhenSelected" and SelectionMode as "Extended". It works great when single row is selected. But when multiple rows are selected, the row details of each row will all be shown which makes the grid looks in a jumble. Is it possible to not show row detail when multiple row are selected but keep show row detail when single row is selected?

I'm using 2014.1.411.45 and MVVM. Thanks.

I am trying to customize the RadTimeline Control Template, however, when I simply Edit Template -> Edit a Copy the style that is created has an error without any modification.  How can I fix this? I think it could be an assembly issue, if so how can I link to the correct assembly? Thanks.

Excuse me, 
I'm trying to use Milestone WPF player (which makes use of VideoOsPlayer) and I got an exception while removing a bounded item to the TileView itemsource.
I've created a sample project thinking the iussue would be on VideoOs player but they answered me 

Thank you for the sample. It allowed us to reproduce the issue, but unfortunately the behavior we observe is quite strange.
What appears to happen is that the DataContext on the controls we have inside the ImageViewerWpfControl are set to null by something outside our code. Our code has no code for setting these to null and no public properties allowing others to do so, so apparently Telerik is running through the children of the control and setting these?

We tried reproducing using normal WPF controls, but could not.
This is not behavior we expect/support and thus the code has not been designed for it.
One thing we found out is that if you set IsVirtualizing="False" on the Telerik control it will not cause the problem, so even though this is not optimal it is at least a workaround.
Maybe you can reach out to Telerik to ask them about this behavior?

Here you can find the whole thread with the link of the demo project

What's really strange is that setting IsVirtualizing="False" it apperently works...can you please check on your side?

I've used 2018.2.620.45 control version

Thanks in advance

Hello Telerik,

I have an expander inside a user control, which is inside of a raddocking's left pane. What I have done is that, I let the expander to decide the width of the docking's left side. But the problem is that as soon as I change the width of the docking manually (I drag the docking's corner to change its width), the mechanism stops, that is, the expander can not change the width of the docking anymore!

I would like to know why and how I can fix it. Any ideas?

Best Regards

I have a visualization layer bound to an observable collection of MapShapeData. There is a LineData in it whose initial points are Location.Empty. As I change Point1 and Point2, the line is correctly updated on the map. When I change Point1 and Point2 back to Location.Empty, the line stays on the map. I am expecting it to disappear.

This was the only simliar thread I saw:
