(Sorry, the title should read "Appointment Changed Event in VB.NET" but I don't seem to be able to change it.)

The RadScheduler has several events:

AppointmentAdded
AppointmentDeleted
AppointmentEditDialogShowing

However, I don't see an AppointmentChanged event or AppointmentEditDialogShown event (or something to let me know that the edit dialog has been closed and I can persist the changes to the database).

Is this by design?

I found in another thread a mention of the RadScheduler.Appoinments.CollectionChanged event but in order to use it I have to use an AddHandler statement, something I'm not accustomed to in VB.

It just seems that an AppointmentChanged event would be an obvious event to implement.

Documentation Winforms UI - RadCommandBar

Hi,

I trying some controls from Telerik.
When searching for some documentation I found a document: https://pt.scribd.com/doc/98627477/Telerik-RadControls-for-Winforms-Courseware. = 775 pages
In that document I can find some usage off the RadCommandBar.
The problem is that I can't freely download that document.
When I look to the same? document on the telerik website I found: http://www.telerik.com/docs/default-source/documents/ui-for-winforms/telerik_ui_for_winforms_courseware.pdf
I should think that these are the same documents but on this I can't find the RadCommanBar entries this domument is only 657 pages (so 118 pages smaller!)

Can someone point me to the latest document for the Winforms documentation (with RadCommandBar entry in it)

regards
Didier

How to make single instance application?

Greetings. I've created Telerik VB Windows Forms Application and have checked the "Make single instance application" check box in the Visual Studio Project Designer. But it doesn't have any effect. When called with command line arguments, application always starts new instance, despite that there is another instance, already running. And the event My.Application.StartupNextInstance is never fired. Is it possible to fix it?

What is the correct way to embed images?

I need to add some custom images to the ribbon, and I am wondering what is the best practice method for doing this.

Here's what I have right now, which is obviously not right. What would be a more elegant approach?

var templateNameImageBytes = Convert.FromBase64String(@"iVBORw0KGgoAAAAN......"); //truncated

var templateNameStream = new MemoryStream(templateNameImageBytes);

var lblTempalteName = new RadLabelElement()

{

Text = "Template Name:",

AutoSize = false,

Size = new Size(120, 20),

Image = Image.FromStream(templateNameStream),

TextImageRelation = TextImageRelation.ImageBeforeText

};
