Problem with creating Form in C# .NET

[wizardrycon]

Hi,

I am fairly new to programming with .NET and have ran into a problem which I can not figure out.

I am trying to create a grid using buttons. This will become an interface for the popular Sudoku game.

I have ran test's and the controls are being added (I verified by checking the contains method return for each control) but the only visible buttons are in the first quadrant (separated into 9 Panels).

Any idea why this is not painting the other buttons? I am stumped!

------------------------------------------------------------------------------------------

Also if anyone knows how I can create the form controls so they automatically size to match the size of the form (i.e. the boxes will grow as the form is stretched out and shrink when pulled back in) I would like to implement that functionality as well.

And since I am new to this environment, any constructive criticism or ways this could be improved would be greatly appreciated.

Thanks!

Sorry, that was dumb for a first post!

I finally figured out the error, it was in my positioning routine for the button inside the panel. Each panel coordinate directly affected where the button was written inside the panel(out of view so it looked like a painting problem).

All better now... For those interested in bug here it is:

The location settings should of read this:

this.GridBtn[x,y].Location = new System.Drawing.Point(32*(x-x1), 32*(y-y1));

Instead of:

this.GridBtn[x,y].Location = new System.Drawing.Point(0+(x*32), 0+(y*32));

Thanks for looking!
