Hello,

We would like to use SyntaxEditor by providing our own programming language definition. It would be great to have the ability to feed SyntaxEditor with a language definition file. This file could be use an EBNF-like format to provide syntax coloration.

Thanks & regards,

If ExportDefaultStyles is set to true, the default styles are exported. If the user has set some settings in the ElementExportingToDocument handler, those are ignored.

Setting the property to false allows the custom setting to be applied, but the default ones are gone

Release LIB 2019.3.1007
The CustomElementLoading event can't be canceled without creating a new instance of the custom element.

As a workaround in the CustomElementLoading event handler you can call the SetAffectedElement() with creating DependencyObject and then Cancel the event by setting the Cancel property.
private void RadDockingOnCustomElementLoading(object sender, LayoutSerializationCustomLoadingEventArgs e)
{
    if (e.CustomElementTypeName == "MyRadPane")
    {
        e.SetAffectedElement(new DependencyObject());
        e.Cancel = true;              
    }
}

The HeaderVisibility property of RadRibbonTab doesn't work when changed at runtime.

A workaround is to use Visibility property of RadRibbonTab, instead of HeaderVisibility

If you update the property value bound to the Value of the cells at runtime, this change doesn't reflect in the UI. To reproduce this you will need to assign a colorizer to the CategoricalDefinintion and set the colorize's IsAbsolute property to True.

To work this around, reset the Definition property of RadHeatMap after the values change.
var definition = this.heatMap.Definition;
this.heatMap.Definition = null;
this.heatMap.Definition = definition;

When you set the Palette property to a new instance of ChartPalette in XAML, a NullReferenceException is thrown. This happens when you click inside the chart control in the Visual Studio designer.

The exception reproduces only if the "Miscellaneous" category in the "Properties" pane of Visual Studio is expanded.

To work this around, set the Palette property in code:

C#:

public MainWindow()
{
    InitializeComponent();
    this.chart.Palette = (ChartPalette)this.Resources("cpBarChart");
}

VB.NET:
Sub New()
    InitializeComponent()
    Me.chart.Palette = DirectCast(Me.Resources("cpBarChart"), ChartPalette)
End Sub

As we now have support for Webcams with RadWebcam-Control how about supporting Twain? But not the old version, instead the platform independent newer Twain-Direct. There is already C# Source Code under MIT-License available: https://github.com/twain/twain-direct. I think this could be used in Xamarin and WinForms, even ASP.NET also...

In this example, the current synchronization context is "occupied" by the task that sets the RTF string forcing the arrange tasks to wait for it to complete before they can start. However, it can never complete as it is blocked by the wait call for the arrange tasks that will never run, causing a deadlock.

When there are items with longer text than the FilteringControl's default width, the FilteringControl resizes when scrolling to these items. This behavior is observed with all themes, different from Windows 8 and Windows 8 Touch.

When the copied document fragment is replaced during paste within a single RadDocument:

ClipboardEx.SetDocument(new DocumentFragment(doc));

Ordered list are not pasted correctly.

Workaround:

Bypass paste and use the InsertFragment API

this.radRichTextBox.InsertFragment(new DocumentFragment(doc));
e.Cancel = true;
