Hi

The natural MonthCalendar control has not provide this functionality. But we can ingore mouse select and key select events. The following code shows how to do this.

Code Block

public partial class MainForm : Form

{

public MainForm()

{

InitializeComponent();

MyMonthCalendar mc = new MyMonthCalendar();

this.Controls.Add(mc);

}

}

public class MyMonthCalendar : MonthCalendar

{

protected override void WndProc(ref Message m)

{

if (m.Msg == WM_LBUTTONDOWN)

{

int x = LOWORD((int)m.LParam);

int y = HIWORD((int)m.LParam);

HitTestInfo info = HitTest(x, y);

if (info.HitArea == HitArea.Date &&

(info.Time.DayOfWeek == DayOfWeek.Saturday ||

info.Time.DayOfWeek == DayOfWeek.Sunday))

return;

}

base.WndProc(ref m);

}

protected override bool ProcessCmdKey(ref Message msg, Keys keyData)

{

return true;

}

private static int HIWORD(int n)

{

return ((n >> 0x10) & 0xffff);

}

private static int LOWORD(int n)

{

return (n & 0xffff);

}

private const int WM_LBUTTONDOWN = 0x0201;

}

Best Regards,
