Custom Resource Group Header Styles?

[Jeff]

I need to modify the style of the group header but can't seem to do it. I can modify the font, but it also seems to modify the font of the appointments as well.

Dim SchedElement As SchedulerDayViewGroupedByResourceElement = RadScheduler1.GetDayView.Scheduler.SchedulerElement.ViewElement
SchedElement.Font = New Font("Segoe UI", 10, FontStyle.Regular, GraphicsUnit.Point)
SchedElement.ForeColor = Color.White
SchedElement.ResourceHeaderHeight = 35
SchedElement.ResourcesHeader.BackColor = Color.FromArgb(0, 159, 60)
SchedElement.ResourcesHeader.BackColor2 = Color.FromArgb(0, 159, 60)

 
Anything that sets a "ResourceHeader" doesn't seem to do what I am expecting. The attached picture shows the header I am trying to modify as well as what RadControlSpy says about it.

Hi Jeff,

Thank you for contacting us. 

If you want to change the color of resource, you need to change the Color of one resource or all resources. Please take a look at the following code example: 

1. Change the color of one resource: 

Me.RadScheduler1.Resources(1).Color = Color.BlueViolet

2. Change the color of all resources:    

Dim colors() As Color = {Color.LightBlue, Color.LightGreen, Color.LightYellow, Color.Red, Color.Orange, Color.Pink, Color.Purple, Color.Peru, Color.PowderBlue}

        Dim names() As String = {"Alan Smith", "Anne Dodsworth", "Boyan Mastoni", "Richard Duncan", "Maria Shnaider"}

        For i As Integer = 0 To names.Length - 1
            Dim resource As New Telerik.WinControls.UI.Resource()
            resource.Id = New EventId(i)
            resource.Name = names(i)
            'set to each resource different color
            'resource.Color = colors(i)
            'set to each resource one color
            resource.Color = Color.FromArgb(0, 159, 60)
            Me.RadScheduler1.Resources.Add(resource)
        Next i

I attached a sample demo project which demonstrates you how to change the color of resource.

When RadScheduler loads it works but when i save the changes with this code (code in the bottom) I lose my styles. How can i keep them? (View Attachment Photo):

01.YDS_CitasDataSet.AppointmentsResourcesDataTable deletedRelationRecords = yDS_CitasDataSet.AppointmentsResources.GetChanges(DataRowState.Deleted)    as YDS_CitasDataSet.AppointmentsResourcesDataTable;

Hello Alejandro, 

Thank you for writing.  

When you save the changes to your database, it is not supposed to change the view element. However, if you refresh the SchedulerElement some of the applied changes may be lost. That is why I would recommend you to apply the changes after the RadScheduler is refreshed. Thus, you will ensure that the design will remain the same. If you are still experiencing any further difficulties, feel free to submit a support ticket where you can provide a sample project demonstrating the problem.

I hope this information helps. Should you have further questions I would be glad to help.

Hi Again.

I tried to figure out the problem but I didn't find where occurs the refreshing method, I tried to submit a support ticket but I'm not the owner of the license. but I make a sample project with the problem, you can get from here: Sample Project in this file Iattached the full project and the sample database with only Radscheduler form and the mentioned behaviour. Can you help me?

Hello Alejandro, 

Thank you for writing back. 

Please ask the purchase holder to add you as a License Developer to the purchase. This will give you full access to the products your company has purchased, to our downloads section, and to our support ticketing system.

I managed to replicate the described problem with the provided sample project. In order to keep the visual settings after saving the changes to your database you can use the following code snippet:

private void BTN_Save_Click(object sender, EventArgs e)
{
    this.Save();
    FormatUI();
    this.radScheduler1.SchedulerElement.RefreshViewElement();
    SchedulerDayViewGroupedByResourceElement headerElement = this.radScheduler1.SchedulerElement.ViewElement as SchedulerDayViewGroupedByResourceElement;
    headerElement.ResourceHeaderHeight = 135;

    RadMessageBox.Show(new Form() { TopMost = true, StartPosition = FormStartPosition.CenterScreen },
        "Information Saved.", "Aviso", MessageBoxButtons.OK, RadMessageIcon.Info, MessageBoxDefaultButton.Button1);
}

I hope this information helps. If you have any additional questions, please let me know.

Thank you Dess. It works. As an Add-on and only for the people who will ask the same in the future. We have to establish the view parameters again like it follows :

private void BTN_Save_Click(object sender, EventArgs e)
       {
           this.Save();
           FormatUI();
           this.radScheduler1.SchedulerElement.RefreshViewElement();
           this.radScheduler1.GetDayView().RangeFactor = ScaleRange.QuarterHour;
           this.radScheduler1.GetDayView().ShowAllDayArea = false;
           this.radScheduler1.GetDayView().WorkTime.Start = new TimeSpan(9, 0, 0);
           this.radScheduler1.GetDayView().WorkTime.End = new TimeSpan(19, 0, 0);
           SchedulerDayViewGroupedByResourceElement dayView = this.radScheduler1.SchedulerElement.ViewElement as SchedulerDayViewGroupedByResourceElement;
           dayView.ScrollToWorkHours();
           SchedulerDayViewGroupedByResourceElement headerElement = this.radScheduler1.SchedulerElement.ViewElement as SchedulerDayViewGroupedByResourceElement;
           headerElement.ResourceHeaderHeight = 135;

           RadMessageBox.Show(new Form() { TopMost = true, StartPosition = FormStartPosition.CenterScreen },
               "Information Saved.", "Aviso", MessageBoxButtons.OK, RadMessageIcon.Info, MessageBoxDefaultButton.Button1);
       }
