Overriding standard selection behavior

SyntaxEditor for Windows Forms Forum

I'm working on a feature that navigates in the document when a token is clicked while the Control key is pressed. To do this I handle the MouseClick event and check whether Control is down. This works but there are several issues:

1. MouseDown event highlights the word if Control is pressed. I want to get rid of this behavior.

2. If the whole word is selected then MouseClick does not trigger. I guess it starts the drag-drop mode. I want to prevent this when Cotnrol is pressed as well.

Any ideas about how this can be done?

Hi Anton,

You can probably handle the SyntaxEditor.ViewMouseDown event.  If you set e.Cancel to true there, it will prevent our behavior.  That is the proper mouse handler to add your code as well.
