Hello everyone,

in my application I have 2 different usercontrol. In first ine I have a RadTileView, In the other usercontrol I have a simple list of element present in the first usercontrol (with a dedicated button) and i want to open the radtile view element by click on the button.

Through this code

 var container = radTileElement.ItemContainerGenerator.ContainerFromItem(item) as RadTileViewItem;

 if (container != null)
 {
    container.TileState = TileViewItemState.Maximized;                 
 }

i can open the Tile view from the other usercontrol, but only if all element of RadTileView are in Minimized state. If a tile view element in the RaTileView is Maximized this call

radTileElement.ItemContainerGenerator.ContainerFromItem(item) as RadTileViewItem;

 return null.

Any suggestions?

Thank you

How to realize for the RadSyntaxEditor?

I'm making a simple file upload application that should only accept Excel files.
I've found out how I need to set the filter on the RadOpenFileDialog and I'm throwing an error (via messagebox) when the extension is wrong when dropping a file on the control.

        public RelayCommand FilePathChangedCommand => new RelayCommand((ea) =>
        {
            if (!string.IsNullOrEmpty(FilePath))
            {
                var extension = Path.GetExtension(FilePath);
                if (!extension.In("xls", "xlsx", "xlsm"))
                {
                    //throw error
                }
                else
                {
                    //process file
                }
            }
        });

When the extension is wrong, I would also like to clear the value in the RadFilePathPicker. But when I make it empty in the FilePathChanged event, it doesn't do anything.

What would be the correct approach to clear the control in this case?

I have this code in xaml:

 <telerik:RadDiagram
     x:Name="RadDiagram"
     primitives:BackgroundGrid.LineStroke="{DynamicResource SelmoBrushDiagramLineStroke}"
    ..../>

The problem is before the colors were predefined. It was a hex value.

Everytime I load the digram xml  with RadDiagram.Load(xml) the LineStroke has the hex color which was saved before in the serialzed xml and the new Dynamic Color doesn't get applied.

Is there any possibility to override the loaded diagram xml, or maybe set the the LineStroke in codebehind after loading the diagram xml?

Hello dear Telerik Forum.

I have a memory leak problem, where opening views add up in memory, because they are still somehow referenced and thus not GCed.

I've implemented Prism and Telerik both in my application. I've also implemented the ScopedRegionNavigationContentLoader,  the RegionManagerAwareBehavior (and everything else required to open views in new tabs) from Brian (Prism) and the RadTabbedWindow in my MainWindow. So when I execute RequestNavigate from the MainWindow I open new Tabs.

Following happens:

When I execute RequestNavigate commands from the MainWindow I successfully open a new tab which then builds the view, existing of multiple subviews. This works correct so far.

Now when I close the RadTabItems the Views still stay in the memory. It seems there are still references in the RegionManager about the once spawned Regions/Views. Those add up when using the application over hours.

So my question is:

How do I unload the Region/View in the RegionManager of the MainWindow when I close the tabs?

I'm looking for a clean and global solution, where I dont have to implement code in every class.

Extra information:

- There is one RegionManager in the MainWindow, which manages all Tabs and so.

- Each Subview gets its own new RegionManager instance.
