need help with Knight's tour game in c# xna

I knocked up a windows forms program to show you a way of doing what you want
It is not finished in as far as it does not check for all invalid moves ( I have done approx half as an example)
Also included is a drawing of available moves numbering

yes the knight is suppose to fill all the spaces in the right order.
thanks

First thing, as you have uploaded your code, edit your post and delete all that code- no one is going to read it.
When i hit space key, the chessboard corrupted - so I made a single image of squares to overcome that.
After a quick look, it sometimes works - the first space key press, but the second press does nothing
So basically you want the knight to move to any allowable random position ?
