Please, answer me,
I reading book "Windows Forms Programming in C# " and part :
void GridForm_Layout(object sender, LayoutEventArgs e) {
// Suspend layout until we're finished moving things
this.SuspendLayout();
// Arrange the buttons in a grid on the form
Button[] buttons = new Button[] { button1, ..., };
int cx = ClientRectangle.Width/3;
int cy = ClientRectangle.Height/3;
for( int row = 0; row != 3; ++row ) {
for( int col = 0; col != 3; ++col ) {
Button button = buttons[col * 3 + row];
button.SetBounds(cx * row, cy * col, cx, cy);
}
// Set form client size to be multiple of width/height
SetClientSizeCore(cx * 3, cy * 3);
// Resume the layout
this.ResumeLayout();
QUESTION
