Currently, the PropertyGroupDescriptor in the DataGrid component does not support grouping by nested properties (e.g., Customer.Address.City). Enhance the PropertyGroupDescriptor to support nested property paths, allowing developers to group data based on sub-properties within complex objects. This would align with common data-binding patterns and improve the flexibility of the DataGrid for real-world scenarios involving nested data models.

Provide an option to sort the template column by nested property. 

For example: 

<dataGrid:DataGridTemplateColumn>
    <dataGrid:DataGridTemplateColumn.CellContentTemplate>
        <DataTemplate>
            <Label Text="{Binding MyAddress.City}" />
        </DataTemplate>
    </dataGrid:DataGridTemplateColumn.CellContentTemplate>
    <dataGrid:DataGridTemplateColumn.SortDescriptor>
        <dataGrid:PropertySortDescriptor PropertyName="MyAddress.City"  />
    </dataGrid:DataGridTemplateColumn.SortDescriptor>
</dataGrid:DataGridTemplateColumn>

When grouping descriptors are set immediately after assigning the ItemsSource on a DataGrid, the descriptors are cleared internally, resulting in grouping not being applied. This occurs because the data engine is still in the process of updating the ItemsSource, and no immediate update is triggered by the added or removed descriptors afterward.

Ran into this issue - which seems to be dependent on how the content gets rendered, so it will fail 100% of the time on specific configurations, resulting in unusable applications.

I've found this issue on Android but there's no telling if the issue is cross platform - as it may depend on item sizings and layout, it may also be reproducible on other platforms, I just haven't hit it yet. The device you run it on may also influence the result, as different resolutions and scalings will impact how items are rendered on screen. I've reproduced this on a Pixel 7 (real device), Samsung A21s (real device) and Pixel 7 Pro (emulator).

Repro steps

  1. Create a new maui sample app, with the relevant Telerik components/initialisation.
  2. Add the xaml and code shown below to the MainPage.
  3. Run the application
  4. OBSERVE
    1. ArgumentOutOfRangeException will be thrown in RadWrapLayoutManager.ArrangeChildren
  5. Stop the app. Comment out the last item being added to the wrap layout and run the app again.
  6. OBSERVE
    1. It will run fine.

MainPage.xaml - use this as the page content:

    <ScrollView Padding="15,0,15,15">
        <VerticalStackLayout Spacing="25">
            <telerik:RadWrapLayout
                x:Name="BrokenLayout"
                Margin="-5"
                SizeChanged="BrokenLayout_SizeChanged"
                StretchLastChild="False">
                <BindableLayout.ItemTemplate>
                    <DataTemplate>
                        <Grid
                            Margin="3.75"
                            Padding="3.75"
                            BackgroundColor="LightGreen">
                            <Label
                                FontAttributes="Bold"
                                FontSize="11"
                                LineBreakMode="TailTruncation"
                                MaxLines="2"
                                Text="{Binding}"
                                VerticalOptions="End" />
                        </Grid>
                    </DataTemplate>
                </BindableLayout.ItemTemplate>
            </telerik:RadWrapLayout>
        </VerticalStackLayout>
    </ScrollView>

Create a blank telerik project (I've not used shell);
Update maui to 9.0.50 (for more relevance with current code);
Replace the contents of MainPage.xaml with the xaml shown below;
Remove unnecessary code from MainPage.xaml.cs to allow app to build and run;
OBSERVE:
Test 1.2 fails - items are shown on a single row when they should not fit.
Test 1.3 fails - items are shown on a single row when they should not fit, and the wrap layout is extended to two rows.
Test 2.1 fails - items are show on two rows when they should fit a single one.
