Is there a sample that shows how to implement rubber band selection using VS2005 C#?

If you mean that you want to give the user the ability to select regions, you can do this by setting the rasterImageViewer1.InteractiveMode to Leadtools.WinForms.RasterViewerInteractiveMode.Region.

If you mean something else, please provide me with more details about your requirements.

Thanks,

I was looking for sample code since I am new to c# & leadtools. I want to be able to create a pan window, similar to what is done in C++, select an area to pan and display that same area on both images.

If you need a sample code that shows how you can create a pan window and pan the image using the mouse, please check the LEADTOOLS C# Main demo that ships with the SDK. You can find the source code of the demo here:
[LEADTOOLS 17]\Examples\DotNet\CS\MainDemo

You can find the code under the _menuItemViewInteractive_Click event.

Thanks. Found that and I got it working. Now what I would like to be able to do is select/create a region of an image and zoom in on that region only, i.e show that region in the viewer. Is this possible & how? The sample that I saw only shows how to create the region.

You can do this by setting the rasterImageViewer1.InteractiveMode to Leadtools.WinForms.RasterViewerInteractiveMode.ZoomTo.

Also, you can do this by selecting a region on the image, and then pass the region rectangle to the RasterImageViewer.ZoomToRectangle() method.

I was trying to use 'Region' mode with the ZoomToRectangleMethod(). I assume I was sending in the wrong values for my rectangle region because it wasn't working as expected. Setting the mode to 'ZoomTo' works. Thanks so much for all your help!

You can draw a region and then zoom to the region rectangle by using the following code:
+------------+
LeadRect Rect = rasterImageViewer1.Image.GetRegionBounds(null);
Rectangle Rect2 = new Rectangle(Rect.Left,Rect.Top,Rect.Width,Rect.Height);
rasterImageViewer1.ZoomToRectangle(Rect2);
+------------+
