Crash when inserting symbol

[Andrew]

I have created a window with a rich text box and the rich text box ribbon control.

I can use it, except for when I attempt to add a symbol.

The steps to crashing it are as follows:

• In the ribbon bar, select Insert
• Click on the Symbol button
• Click on any symbol

It then crashes with an ArgumentNullException, somewhere inside the function:

              SymbolsTable.cell_MouseLeftButtonUp(object, System.Windows.Input.MouseButtonEventArgs)


I have a demonstration application for this bug, encompassed in one .XAML file:

Hi,

Is there any feature like subscript or superscript for a label or textblock. I want to implement the lable or textblock name some what like this,

eg: Kg/Cm2

Here '2' should be the superscript of the "Kg/Cm". How can I achieve this. Please suggest me any workarounds available.

Thanks & Regards
K Siva Prakash.

Hello K Siva Prakash,

RadRichTextBox supports superscript and subscript. You can preview them in our ClickOnce demo.
The two buttons in the Home tab, Font ribbon group are bound to ToggleSuperscriptCommand and ToggleSubscriptCommand. You can also use these commands programmatically, if you are building your own UI.

In case you are building the document in code-behind, you can create it like this:

RadDocument document = new RadDocument();
Section section = new Section();
document.Sections.Add(section);
Paragraph paragraph = new Paragraph();
section.Blocks.Add(paragraph);
Span span = new Span("Kg/Cm");
Span superScriptSpan = new Span("2") { BaselineAlignment = Telerik.Windows.Documents.Model.BaselineAlignment.Superscript };
Span spanInterval = new Span(" ");
paragraph.Inlines.Add(span);
paragraph.Inlines.Add(superScriptSpan);
paragraph.Inlines.Add(spanInterval);
this.editor.Document = document;
