When the variation is changed in the VisualStudio2013 theme, the Foreground is not updated. 

As a workaround, you can reset the Template of the control:

var template = this.syntaxEditor.Template;
this.syntaxEditor.Template = null;
this.syntaxEditor.Template = template;

When the control is inside ScrollViewer and you click it, focus is lost and caret disappears. Some controls have built in ScrollViewer , for example LayoutControl so placing the editor in LayoutControl also leads to the same issue.

Generally placing the syntaxeditor in scrollviewer is risky for the vertical virtualization so at least a height should be set to the control. In R2 2020 SP, an exception will be thrown if Syntax Editor with no height is added in scroll viewer or stack panel or other panel which measures vertically with infinity.

Workaround for this issue:

        private void syntaxEditor_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
        {
            e.Handled = true;
        }

SyntaxEditor is in RadListBoxItem.

Entering space key does not produce text change and gets the focus lost our of the editor.

Workaround:

    private void RadSyntaxEditor_PreviewKeyDown(object sender, KeyEventArgs e)
        {
            if (e.Key == Key.Space)
            {
                (sender as RadSyntaxEditor).Insert(" ");
                e.Handled = true;

Hello,

When we resize the syntaxEditor control, the folding buttons moved. You can reproduce this isssue in your demos.

 

  1. Reduce the contents of the sample
  2. Increase the size of sample window and see the buttons are not besides the line

 

Best regards,

In some cases the string values in the XML attributes are not colored with the expected color, but default to black.
 
This was reproduced when there is only single quotation mark on visible on the line. And also if the count of the visible quotation marks on the line is an odd number (not always reproducible).

If you have an XML attribute with a string value, but the value is not fully rendered into the viewport, its color defaults to black, instead of the expected blue color.

To work this around, you can create a custom XmlTagger and override its GetTags() method. This will allow you to properly catch the string value and return it as a tag span element with its ClassificationType set to "string".

Folding tagger does not work for other languages than C#.
It should be renamed to CSharpFoldingTagger.
FoldingTagger should be base , extensible class with options to set collections of opening symbols (brackets) or words (for startinga  method / class, region) and closing symbols / words.

For example "//====" will not be commented in C#. 
Or "!====" wont' be commented in custom language if "!" is the commenting symbol.
The issue resides in the word splitting function in WordTaggerBase class.
