On WinForm I have added WPF control (Infragistic's XamSyntaxEditor)

I have added ElementHost on my Form .(Need to add reference to System.Windows.Forms.Integration)

In my Form Load after Initialise component.

I have writtn below code :

Dim Document As TextDocument = New TextDocument()
Document.Language = New Infragistics.Documents.VisualBasicLanguage

' WPF control which I want to add on Form
Dim editor As XamSyntaxEditor = New XamSyntaxEditor()

editor.ErrorDisplayMode = SyntaxErrorDisplayMode.Never
editor.SplitOptions = EditorDocumentViewSplitOptions.SplittingNotAllowed
editor.Document = Document
host.Dock = DockStyle.Fill
host.Child = editor

Control is getting added on ,works fine .

But I am not able to trap any input /change evnt on this control.

How to communicate with Control .

I tried to hook event mentioned as below link :

Hi Stefan ,

Using Append method crash doesnt occured in code which I have provided , But if I use append instead of initialize text in my actual class crash still exist.

Also if append intead of initialize text doesnt serv the actual purpose , even if I add condition checks etc in some scenarios text get appended .

What is exact cause of this error ? How I can resolve it ?

Hello Aparna,

I have been looking into the sample you have attached and I was able to reproduce the first exception you mentioned and I can suggest you use the Document's Append method instead of InitializeText one on the setter of the Text property. Could you please try this and see if the second exception will continue to occurs.

Looking forward for your reply.

Hi Stefan ,

I have attached sample which reproduce crash mentioned above .

(Note : To run EXE you need to change Infragistics DLL references to yur local DLL references,I have removed DLL as f they were causing huge size of zip file upto 6MB )

When you run EXE 1st time you will get Argumet exception in TextDocument and Compatability Error .

On Compatibility Error when youe click on Close button .

Again Run EXE now you will get argumentNullReference Exception in XamSyntaxEditor ,related to parameter 'newOrReformattedLines'

Looking forward for your feddback on this issue.

Hello Aparna,

I have been looking into the exception, but since this is not a known issue, without a sample project, where this is reproduced we are not able to investigate this further for you.
