Graghic elements selection

[AnatoliiTerentiev]

Dear Gurus!

Can't anybody help to find - how to implement graphic elements selection similarly with the "i" instrument in arcmap?

I will explain the problem, required the following.

User click the point on the map, moving the mouse without releasing the button, draw the rectangular polygon.

After releasing the button - all elements, which fall into a rectangle - become selected. I wonder - how to draw a polygon. In WPF , silverlight the problem is solved with "Draw" object.

There are exists instrument - "Select elements" in standart tools for selecting elements and "Identify" tools to select  features in rectangle. But to combine these tools into one, i.e. highlight both the elements and properties, I would like to understand how to obtain the polygon (rectangle), using the above mouse actions,  and then to find features and elements inside it (just the same as with Draw object in silverlight).
