I want to draw a line.
I use this code
But the previous line is visible.
private void OnMouseDown(object Sender, MouseEventArgs Args)
StartPoint = Args.GetPosition(DrawingCanvas);
private void OnMouseMove(object Sender, MouseEventArgs Args)
if (Args.LeftButton == MouseButtonState.Pressed)
EndPoint = Args.GetPosition(DrawingCanvas);
DrawLine(StartPoint, EndPoint, DrawingCanvas);
private void DrawLine(Point From, Point To, Canvas TargetCanvas)
CurrentLine = new Line();
CurrentLine.StrokeEndLineCap = PenLineCap.Round;
CurrentLine.StrokeStartLineCap = PenLineCap.Round;
CurrentLine.Stroke = Brushes.Red;
CurrentLine.StrokeThickness = 2.0;
CurrentLine.X1 = From.X;
CurrentLine.Y1 = From.Y;
CurrentLine.X2 = To.X;
CurrentLine.Y2 = To.Y;
How can I avoid that??
Thanks & Regards

Re: Draw Line
Well, this is sort of obvious, since it's exactly what your code does: It creates a new Line object on every MouseMove event. I guess what you intended is to create the new line in your MouseDown handler, and change only its end point when the mouse is moved?
