How to clear microsoft ink picture control?

问题

Say I draw something and I have a button to clear , how do i clean/clear/reset the drawing on the control ?

回答1:

Well so far as I found out say I have a button to clear I just need to

inkPicture1.InkEnabled = false;
inkPicture1.Ink = new Microsoft.Ink.Ink();
inkPicture1.InkEnabled = true;
inkPicture1.Invalidate();

so that the control gets instantiated with a new ink object.

MSDN Reference: http://msdn.microsoft.com/en-us/library/ms701123%28v=vs.85%29.aspx

Get a refrence to the Ink Display object from the InckPicture's Ink property.

Then use the InkDisp.DeleteStrokes() method and pass InkDisp.Strokes property as Parameter.

Example:

            control.Enabled = false;
            control.Ink.DeleteStrokes();
            control.Enabled = true;
