Is this possible?

Thanks

Hi Mattl,

Thank you for your question.

You can achieve this by creating and using a descendant class of RadScheduler. The following code snippet demonstrates how you can achieve this:

public class MyScheduler : RadScheduler
{
    public override void InvalidateElement(Telerik.WinControls.RadElement element)
    {
        if (this.ActiveViewType != SchedulerViewType.Timeline)
        {
            base.InvalidateElement(element);
            return;
        }

        foreach (RadElement child in (this.SchedulerElement.ViewElement as SchedulerTimelineViewElement).Presenter.Children)
        {
            SchedulerCellElement cell = (child as SchedulerCellElement);
            if (cell != null)
            {
                if (cell.Date.DayOfWeek == DayOfWeek.Sunday || cell.Date.DayOfWeek == DayOfWeek.Saturday)
                {
                    cell.BackColor = Color.Red;
                }
                else
                {
                    cell.ResetValue(RadItem.BackColorProperty, ValueResetFlags.Local);
                }
            }
        }

        base.InvalidateElement(element);
    }

    public override string ThemeClassName
    {
        get
        {
            return typeof(RadScheduler).FullName;
        }
        set
        {
            base.ThemeClassName = value;
        }
    }
}

I hope this is helpful. Feel free to ask if you have any additional questions.

That works nicely.

I have updated my form with the inherited version of the control by updating the designer.vb file but is there a way I can do this in code in a similar way the drag & drop example assigns the MyGridBehavior class to

NameOfGrid.GridBehavior = New MyGridBehavior()

Thanks

Hello Mattl,

This is not possible in this case, because you are inheriting directly from the main RadScheduler control and not from a part of it.

Do not hesitate to ask if you have any further questions.

Hello I used the code snippet provided above but when I try to change the view type to timeline I get a NullReferenceException exception. Why is this happening?
Thanks.

Hello Norkitt,

Thank you for writing.

This is happening, because when you switch between views, the ActiveViewType property is changed, but some of the elements are initialized yet. I have updated the previously posted code, so that the exception does not occur. Below is the modified sample:

public override void InvalidateElement(Telerik.WinControls.RadElement element)
 {
     if (this.ActiveViewType != SchedulerViewType.Timeline)
     {
         base.InvalidateElement(element);
         return;
     }

     SchedulerTimelineViewElement timelineElement = this.SchedulerElement.ViewElement as SchedulerTimelineViewElement;
     if (timelineElement == null || timelineElement.Presenter==null)
     {
         return;
     }

     foreach (RadElement child in timelineElement.Presenter.Children)
     {
         SchedulerCellElement cell = (child as SchedulerCellElement);
         if (cell != null)
         {
             if (cell.Date.DayOfWeek == DayOfWeek.Sunday || cell.Date.DayOfWeek == DayOfWeek.Saturday)
             {
                 cell.BackColor = Color.Red;
             }
             else
             {
                 cell.ResetValue(RadItem.BackColorProperty, ValueResetFlags.Local);
             }
         }
     }
}

I hope you find this useful. Do not hesitate to ask in case you have any additional questions.

Best wishes,

In this example, the weekends have their color in red, to show its weekends.
How do one set this in the kendo scheduler?
