I have tried to do a Track ZoomIn like Desktop version of MapSuite (user draw a rectangle in screen), but my redraw is slowly, because I draw the rectangle every Map mouse move event and after invoke Map.refreshDynamic().

How Can I solve this problem?

Hi aztom,

You can set Map1.Mode = ModeType.TrackZoomIn;
to track zoom in, it is just like DesktopEdition.

Hello lijun

But, if I do it, the rectangle doesn't paint on display...
I set Map1.Mode = ModeType.TrackZoomIn, but I want to draw a rectangle like DesktopEdition...

Hi,

It looks like that you have a way to draw the rectangle like DesktopEdition, but it is slow. Am I right?
If so, could you paste pieces of code to let us know how you did it? Maybe we could help you to find out the slowly reason.

I wonder why you call Map.RefreshDynamic in the MouseMove event. To solve the problem of slow drawing of the Rectangle while TrackZoomIn, you would need to remove Map.RefreshDynamic from the MouseMove event.

I try to remove RefreshDynamic, but If I do this, the rectangle doesn't refresh when user "mouse move" on Map.

Can you help-me ?
