EditRecurrenceDialog OK button result is incorrect

I call the EditRecurrenceDialog dialog from a custom editappointment dialog from the buttonRecurrence button.

EditRecurrenceDialog os displayed correctly and I can edit as expected, I click the OK buttin and diag reult is NONE. Screen is reshown and I repeat making selections and click OK button again and result is now OK and rule is created.

Why does OK button result is None first time? Here is complete code for buttonRecurrence

Note: customAppt is scheduler mapped fields and custom fields loaded in single object

private void buttonRecurrence_Click(object sender, EventArgs e)
{
customAppt.RecurrenceRule = recurrenceRule;

using (EditRecurrenceDialog recurrenceDialog = new EditRecurrenceDialog(customAppt))
if (recurrenceDialog.ShowDialog() == DialogResult.OK)
{
var updatedRule = customAppt.RecurrenceRule;
lblRecur.Text = updatedRule.ToString();
recurrenceRule = customAppt.RecurrenceRule;
}
}

Scroll Schedule when dragging appointment

Hi,

In week view, is it possible to auto scroll the schedule when dragging the appointment to the right or left edges of the current view, thus allowing appointments to be dragged into another week?

Does anyone have any working sample code?

Thanks

Split day into multiple slots in grouped-by-resources timeline view radscheduler?

I have a grouped by resources scheduler in timeline view with the timescale set to days and I'd like to set the so called "slot-duration" to half-day for the day cell, which can already be done in the aspnet ajax version I link below. Is there a way to achieve this functionality in c# winforms?

Basically I'd like to divide the day slots into two parts to track absences, which can have a half day and full day duration.

RadScheduler - Adding events programmatically.

I am using the radScheduler for the first time. I am trying to bind some data to it (or even add events programmatically) that we are receiving from an RRS feed. Is there a simple way to do this. The Help files are more about binging a table/dataset to it. Note, this control is used as a READ only view of events for my customers.

TIA for the help

[Solved] Custom AppointmentElement diplay problem

Hello,

I have implemented a custom AppointmentElement and I habe a small display problem with it.

Here is a screenshot:

When the area of the appointment gets to small, the arrow on the right is no longer drawn, but i want the element to always draw it and cut the text first.

Here is my implementation:

internal class CustomAppointmentElement : AppointmentElement
{
    private AppointmentsViewModel _appointmentsViewModel;
    private DockLayoutPanel _outerContainer;
    private StackLayoutElement _container;
    private LightVisualButtonElement _expandCollapseButton;

        _container.Children.Add(_icon1);
        _container.Children.Add(_icon2);
        _container.Children.Add(_icon3);
        _container.Children.Add(_timeText);
        _container.Children.Add(_summaryText);

        DockLayoutPanel.SetDock(_container, Telerik.WinControls.Layouts.Dock.Left);
        _outerContainer.Children.Add(_continueArrow);
        DockLayoutPanel.SetDock(_continueArrow, Telerik.WinControls.Layouts.Dock.Right);
        _outerContainer.Children.Add(_container);

        Children.Add(_outerContainer);
    }
}

Hope you could help me solve it.

Stephan
