Questions on UI for WinForms Forum

In the "Demo Application - UI for WinForms Q1 2016 SP1" there is an example of the RadGridView with Row Details.
I'm trying to reproduce this in the OpenEdge programming platform (so need to to make some minor changes) but I don't get it to work!
The latest problem is that it looks like 'DetailsColumn' is not a valid property of the RadGridView (or there is an error in the docs).

The adjusted code is:
method private void RadGridViewDetails_Load( input sender as System.Object, input e as System.EventArgs ):
            // TODO: This line of code loads data into the 'nwindDataSet.Employees' table. You can move, or remove it, as needed.
/*            this.employeesTableAdapter.Fill(this.northwindDataSet.Employees); */

            this-object:radGridView1:ReadOnly = true.
            this-object:radGridView1:AllowColumnReorder = false.
            this-object:radGridView1:AllowColumnResize = false.
            this-object:radGridView1:AutoSizeColumnsMode = Telerik.WinControls.UI.GridViewAutoSizeColumnsMode:Fill.
            this-object:radGridView1:AutoExpandGroups = true.
            this-object:radGridView1:TableElement:RowHeight = 40.

            this-object:radGridView1:GroupDescriptors:Add(new Telerik.WinControls.UI.GridGroupByExpression("City GroupBy City")).
            /* this-object:radGridView1:Groups[1][0]:IsCurrent = true. */

            this-object:radGridView1:Columns["Photo"]:VisibleInColumnChooser = false.
            this-object:radGridView1:Columns["Photo"]:IsVisible = false.
            this-object:radGridView1:Columns["Notes"]:WrapText = true.
            this-object:radGridView1:Columns["LastName"]:SortOrder = Telerik.WinControls.UI.RadSortOrder:Descending.

            this-object:radGridView1:DetailsColumn = this-object:radGridView1:Columns["Notes"].
       return.

   end method.

The error I get is: Could not locate element 'DetailsColumn' in class Telerik.WinControls.UI.RadGridView
I'm I doeing something wrong here??

Also you notice that I commented this-object:radGridView1:Groups[1][0]:IsCurrent = true.
That's because this is not allowed in OpenEdge? What does this statement mean? Maybe I can transform that so it is allowed in OpenEdge.

What is not clear to me in the example is what code is responsible for adding that DetailsRow?
So what property creates that (default hidden) row that is displayed when I click on a row in the RadGridView

Thanks

Force connection to Left connector

Just researching this component to see if it can do what I want.

I have slightly modified the 'First look' example to see if I can modify it to suit.

From reading the documentation, I should be able to force the connector to attach to a shape on one side , but I cannot get it to work.

As a simple test I tried to add a connection between a member to a Node

Private Sub PopulateWithData()

Dim dataXml As XElement = XElement.Load("Organization.xml")

For Each element As XElement In dataXml.Elements("Node")

Dim node As OrgContainerShape = Me.CreateNode(element, Nothing)

node.BaseColor = Me.groupColor(0)

Me.RadDiagram1.AddShape(node)

currentLayoutSettings.Roots.Add(node)

Me.GetSubNodes(element, node, 2)

Next

'------- Add a new connection as a test -------------------------------

Dim connection As New RadDiagramConnection()

connection.ConnectionType = Telerik.Windows.Diagrams.Core.ConnectionType.Polyline

Dim parentNode = Me.RadDiagram1.Shapes(0)

Dim destNode = Me.RadDiagram1.Shapes(7)

connection.Source = parentNode

connection.Target = destNode

connection.SourceConnectorPosition = "Left"

connection.TargetConnectorPosition = "Auto"

Me.RadDiagram1.AddConnection(connection)

End Sub

But it always connects to the bottom of the shape.

What am I doing wrong? ( I have checked and the shape does have a Left connector)

Many thanks

Rob

Appoint Changed Event in VB.NET

(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

};
