Selection after undo

SyntaxEditor for Windows Forms Forum

Just a quick question

In syntax editor, when undoing a document modification that was caused by completion of the member list, the text range that was associated with the member list is highlighted - is there any way to change this behaviour?

I've tried to find reference to it in the documentation, but I can't find which document modification types cause this behaviour, and if there is any way to change it...

Thanks

Matt

Hi Matt,

Sorry but I don't believe there is any way for you to alter that behavior right now.

Hello,

Thanks for the update. I have worked around it in a crude way by adding the following code in the handler for UndoRedoStateChanged on the document: 
if (e.ChangeType == UndoRedoStateChangeType.Undo)
{
    if (e.Modification.Type == DocumentModificationType.AutoComplete)
    {
        if (shtb.SelectedView.Selection != null && shtb.SelectedView.Selection.TextRange.Length > 0)
        {
            shtb.SelectedView.Selection.StartOffset = shtb.SelectedView.Selection.TextRange.EndOffset;
        }
    }
}
Can you see any problem with that?

Thanks

Matt

That will probably work fine.
