Hello Cooper,

Thank you for writing.
1. Yes, you can do that with the properties you mentioned. To make it easier, just reset them to their default values prior setting the new range:

void radDropDownList1_SelectedIndexChanged(object sender, Telerik.WinControls.UI.Data.PositionChangedEventArgs e)
{
    SchedulerDayView dayView = radScheduler1.GetDayView();

    dayView.RulerStartScale = 0;
    dayView.RulerEndScale = 24;
    switch (e.Position)
    {
        case 0:
            dayView.RulerStartScale = 9;
            dayView.RulerEndScale = 12;
            break;
        case 1:
            dayView.RulerStartScale = 13;
            dayView.RulerEndScale = 17;
            break;
        case 2:
            dayView.RulerStartScale = 18;
            dayView.RulerEndScale = 23;
            break;
    }
}

2. You can set the range to be displayed in 15 minutes style, but the numbers (15,30,45) will not be displayed. to change the scale you can use the RangeFactor property:

SchedulerDayView dayView = radScheduler1.GetDayView();
dayView.RangeFactor = ScaleRange.QuarterHour;

More information about this view is available here: http://www.telerik.com/help/winforms/scheduler-views-day-view.html.

I hope this helps.

Hello Cooper,

Thank you for getting back to me.

In order to detect which item from the context menu is selected, please have a look at the following code snippet:

public Form1()
{
    InitializeComponent();

    this.radScheduler1.ContextMenuShowing += radScheduler1_ContextMenuShowing;
}

private void radScheduler1_ContextMenuShowing(object sender,
    SchedulerContextMenuShowingEventArgs e)
{
    e.ContextMenu.PopupClosing -= ContextMenu_PopupClosing;
    e.ContextMenu.PopupClosing += ContextMenu_PopupClosing;
}

private void ContextMenu_PopupClosing(object sender, RadPopupClosingEventArgs args)
{
    RadDropDownMenu menu = sender as RadDropDownMenu;
    RadItem item = menu.GetSelectedItem();
    if (item != null)
    {
        Console.WriteLine(item.Text);
    }
}

Please do not hesitate to contact us if you have any additional questions.
