NotImplementedException is thrown if the ItemsSourceProvider property is set in a Style setter.

To work this around, implement custom GridViewItemsSourceProvider and override its CreateInstanceCore method.

public class CustomGridViewItemsSourceProvider : GridViewItemsSourceProvider
{
	protected override Freezable CreateInstanceCore()
	{
		return new CustomGridViewItemsSourceProvider();
	}
}

ArgumentNullException is thrown in the GetNameCore method of the RadGlyphAutomationPeer class. This happens when the Glyph property of RadGlyph is not set and the automation peer for the corresponding element kicks-in.

To work this around, disable the automation peers.

AutomationManager.AutomationMode = AutomationMode.Disabled;

ArgumentException occurs when the ItemsSource of the chart series is populated with items that implement the ICustomTypeProvider interface and the value binding properties of the series  (ValueBinding, CategoryBinding, YValueBinding, XValueBinding, etc.) are assigned to dynamic properties. This happens when the value binding properties are assigned to PropertyNameDataPointBinding object pointing to a property name. This is also what happens if you set the properties in XAML using string values.

To work this around, you can use the GenericDataPointBinding<T> class defined in code-behind in order to assign the value binding properties. 

Or alternatively, you can implement custom PropertyNameDataPointBinding class and override its GetValue() method. In the method, you can check the item type and if it is ICustomTypeProvider, and then execute custom code that gets the value. The custom PropertyNameDataPointBinding implementation is shown in the attached CustomPropertyNameDataPointBinding.zip file. To use the custom binding class in XAML, you can use the following syntax:

<telerik:ScatterPointSeries.YValueBinding>
	<local:CustomPropertyNameDataPointBinding PropertyName="Y" />
</telerik:ScatterPointSeries.YValueBinding>

The SeriesCreated event of the RadChartView's SeriesProvicer is never called when the SeriesDescriptorSelector property is used.

To work this around, you can create a custom chart series descriptor and override its CreateInstanceCore method.

public class CustomScatterSeriesDescriptor : ScatterSeriesDescriptor
{
	protected override ChartSeries CreateInstanceCore(object context)
	{
		var series = (ScatterSeries)base.CreateInstanceCore(context);
		// assign whatever settings you need here
		return series;
	}
}

The background of the GridView's group headers has a light background in the dark color variation of the Windows 11 theme. 

This reproduces only the GroupRenderMode property of RadGridView is set to Nested (the default value).

To work this around set the  GroupRenderMode property of RadGridView to Flat.

Hi,

We have noticed another issue with the Toolbar when using Windows 11 Theme.

If we have a toolbar with 3 items, as below:

This looks fine. But if we change the scale settings in windows to be 125%, then we see the following:

This persists even if you have rebooted since changing the scale.

I so not see this with a different theme.

Sample attached.

Please note that this is using the internal 2022.3.1128 hotfix build, which does fix the issue that we were previously seeing with the item layout. It is also present in 2022.3.912.

Thanks

Carl
