Background:
When you place a tile on the form it is placed inside the group. X and Y property of tile returns the coordinates of tile with respect to the parent group of that tile.
Steps to Complete:
To find the co-ordinates of the Tile with respect to the form, handle the Click event of the Tile as given in code snippet below:
int x_cor; int y_cor; private void tile_Click(object sender, EventArgs e) { Tile myTile = (Tile)sender; if (myTile.Group!=null) { x_cor = myTile.X + myTile.Group.X; y_cor = myTile.Y + myTile.Group.Y; MessageBox.Show(string.Format("X:{0},Y:{1}", x_cor, y_cor)); } }
