Hi,
I have an application with Diagram using GraphSource.
Actually i add Container with default styledefine by StyleSelector and i would like to allow my user to choose a different style.
How can i do this ? If i use SelectedItem, i have a model not a shape or container so i can't define style.
Thanks for your help.

I have stumbled upon an issue that has me baffled. I am using v2017.2.503.45 of the Telerik WPF UI and loading up a RadGridView with about 150 records and 16 columns of data - 3 of the columns are GridViewComboBoxColumns and the rest are GridViewDataColumns. On the RadGridView I have:
LoadingRegistrations is set to true in an async method that uses await Task.Run(...) to retrieve the records and assign them to the Registrations property which is an ObservableCollection<Registration>. Within my App.xaml.cs I have:
Using the Office 2016 theme no busy indicator is displayed. If I remove that line from App.xaml.cs or change it to use the Windows 7 theme, for example, the busy indicator is displayed, but it does not animate. I'm OK with the no animation, but why does the indicator not even display when using one of the more modern themes (I have tried several and none of them display the indicator).

I am trying to create a WPF page that can scroll like a carousel a whole panel of controls at a time.
Similar to hero images on websites, we would like a visual indicator of the number of panels and arrows for the user to press to move to the next panel (the carousel shouldn't automatically rotate).
I actually don't know which control (or combination of controls) to use to achieve the effect.
I have attached an image of the wireframe for reference.
Just a nudge in the right direction would really help!
Thanks

In a RadGridView, I am trying to change the border around the cell which has focus. Currently it appears as a faint grayish color, my boss has asked that I make it a darker, thicker border. Not having any luck so far. Why won't the Style definition below work?
<telerik:RadGridView.Resources>
<Style TargetType="telerik:GridViewCell">
<Style.Triggers>
<Trigger Property="IsCurrent" Value="True">
<Setter Property="BorderBrush" Value="#000000" />
<Setter Property="BorderThickness" Value="2" />
</Trigger>
</Style.Triggers>
</Style>
</telerik:RadGridView.Resources>

If I try to load a PDF that has several layers with the RadPdfViewer then all layers are shown but how do I allow the user to decide what layers should be shown?
I cannot find any way in the viewer where I can set what layers should be shown.
In any standard pdf viewer you are able to manage what layers you want to see e.g. to show layer 1 and 3 but not 2.

RadGridView is a really good Grid but the edit experience is terrible...
I try to explain my problems with a check box column.
1) I click it, nothing happens but perhaps now the cell is selected, the style is a little bit changed
2) I click a second time, nothing. But perhaps now the style of checkbox is changed, now it is enabled
3) I click a third time, good now the check is box checked but the Item source value is not change, we are waiting for a magical "CellEditedEndEvent", why???
4) I press the enter key, now the value is really changed.
Now suppose that a user must check 100/200 items/day, it is the work of this user, why we are asking to user "please click 500/1000 time per days instead please..."

I just switched to the TreeListView from TreeView and I have a couple of simple questions.
My collection is structured in a hierarchial type of structure. So there is only 1 item with children, children of children, children of children of children, etc.
Is this the best way to format the collection or should I keep the collection "flat?"
I want to be able to support drag/dropping and persisting an order as the user drags/drops. All of the examples I've seen seem to be using a flat type of collection so it is easy to use the TreeListView index.
Thoughts?
Thanks,
