Question

I am using the WPF Calendar that is part of the WPF Toolkit.

I have two different calendars on a control. When I attempt to choose a date from one calendar and then from the second calendar, I have to click on the second calendar twice to get it to choose a date.

Has anyone else had this issue and know of a solution?

Answer 1

The calendar can capture the mouse without a date change (e.g. in CalendarMode drill down).
A better solution is this:

protected override void OnPreviewMouseUp(MouseButtonEventArgs e)
{
    base.OnPreviewMouseUp(e);
    if (Mouse.Captured is CalendarItem)
    {
        Mouse.Capture(null);
    }
}
