Week numbers

[PÄR-OSKAR HOLMGREN]

Hi

We're currently using the radscheduler in a project and have recieved a request for week numbers to be displayed in Day and Week view. Is there date format for week number or a way to insert a string containing a week number in the header?

with kind regards

Hello PÄR-OSKAR HOLMGREN,

RadScheduler does not support this functionality out-of-the-box but the desired effect still can be achieved in the following way:

1. Override the OnPreRenderComplete event handler of the page.
2. Get the current week number in the event handler.
3. Put the week number in the text of the Header wherever it is appropriate.

Below is the code of the overridden OnPreRenderComplete event handler:

    protected override void OnPreRenderComplete(EventArgs e)
    {
        base.OnPreRenderComplete(e);

        LiteralControl literal = (LiteralControl) RadScheduler1.Controls[0].Controls[0].Controls[2].Controls[0];

        int weekNumber = this.GetWeekNumber(this.RadScheduler1.SelectedDate);

        if ((this.RadScheduler1.SelectedView == SchedulerViewType.DayView) ||
            (this.RadScheduler1.SelectedView == SchedulerViewType.WeekView))
        {
            literal.Text += " Week#" + weekNumber.ToString();
        }
    }

The tricky part here is to find the LiteralControl where the Date is displayed in the Header. This - RadScheduler1.Controls[0].Controls[0].Controls[2].Controls[0] - is exactly where the control is located.

As you see, this approach is not the best. We will surely consider including a support for changing the Header Date Format in a more flexible way in future versions of RadScheduler.

All the best,
