Ribbon MVVM (Gallery Binding)

[Sergey]

Hello dear developers,

I have one question.

I have tried to bind to Gallery with MVMM but I couldn't do it.

At first I created DataTemplate for Syncfusion Gallery.

Here is it.

<DataTemplate DataType="{x:Type vm:GalleryViewModel}">

            <ContentControl>
                <sf:Gallery VisualMode="Standard">
                </sf:Gallery>

            </ContentControl>

 </DataTemplate>

After that I compiled my application and got empty RibbonGroup.

Ok. it is normal bacause I did not set ItemSource for Gallery.

I set ItemSourse to Gallery DataTemplate and got this:

<DataTemplate DataType="{x:Type vm:GalleryViewModel}">

            <ContentControl>

                <sf:Gallery VisualMode="Standard"

                            ItemsSource="{Binding Items}">

                </sf:Gallery>

            </ContentControl>

        </DataTemplate>

After build and run application I got a strange exception.

An unhandled exception of type 'System.InvalidCastException' occurred in Syncfusion.Tools.WPF.dll

Additional information: Unable to cast object of type 'TestGalleryBinding.ViewModels.GalleryCategoryViewModel' to type 'Syncfusion.Windows.Tools.Controls.GalleryGroup'.

Could you explain me how I should make DataTemplate for Gallery, GalleryGroup and GalleryItem?

I attached sample that describes this problem.

Yours faithfully,

Sergey Vlasov
