Yeah, I thought it was someone else, once I knew it was him, I presumed the same.

Thing is - you look at the original post on this thread. Nothing is obvious, anymore. Like I said, when I saw it was you, it was obvious to me. I didn't notice, and not knowing who posted, it was not obvious to me.

If you're new to C# in general, you may be biting off more than you can chew.

you want to drag and drop a rectangle, the typical way to do this is to handle mouse events to track mouse position and button status, and keep calling Invalidate() in your mouse move after updating the co-ordinates that your OnPaint will use to draw the rectangle. When you finish dragging, you need to store the location, so your onpaint continues to draw it.

Did you also expect to 'pick' a rectangle to drag by clicking on it ? To do that, you work out the co-ordinates of your mouse down and iterate through your list of rectangles, to find out which one the mouse is in.

Can i give some mouse event to this rectangle?

Christian Graus4-Jul-07 5:17

No, the rectangle is not a control. In WPF, you can. But, if you're drawing a rect yourself, it's not a control, it can't get an event.

You've not given any offense, not at all.

It's a fair bit of code, I can't just whip it up for you. The core thing to understand, is to get your rectangles drawing in a paint event, and to have the ability to change the location of one ( or create a new one ), based on mouse events. I'd start with a List<Rectangle> and a Paint event that draws the rectangles. Then I'd write the code to get mouse events, and draw a rect. Then I'd write the bit that finds a rect based on a click, and moves it.

Feel free to ask questions any step of the way, but I'm afraid I am unable to jsut write all that for you. If you ask specific questions as you go, I'll be more than happy to help any way I can
