Problem with cusotm objects deserialization

Hello,

I have some problems when I try to deserialize custom objects which implements RadDiagramShape.

I have implemented a custom shape :

public class MyShape : ElementShape

{

public override GraphicsPath CreatePath(System.Drawing.Rectangle bounds)

{

GraphicsPath path = new GraphicsPath();

path.AddString("Custom", new System.Drawing.FontFamily("Arial"), 0, bounds.Width, Point.Empty, StringFormat.GenericTypographic);

return path;

}

And a custom diagramShape :

public sealed class MyDiagramShape : RadDiagramShape

{

public MyDiagramShape()

{

ShapeText = "";

ElementShape = new MyShape();

InternalElementColor = System.Drawing.Color.LightBlue;

}

I add this custom shape to my diagram:

MyDiagramShape diagramShape = new MyDiagramShape();

diagramShape.Position = new Telerik.Windows.Diagrams.Core.Point(100, 80);

radDiagram1.AddShape(diagramShape);

This works fine, and when I serialize, I get a XML like this:

<RadDiagram>

<Shapes>

<MyDiagramShape Type="WindowsFormsApplicationCustomShape.MyDiagramShape"

</Shapes>

</RadDiagram>

Problems come when I try to load this XML, object instanciated are typed as RadDiagramShape and not MyDiagramShape.

When I serialize again, the structure of the XML is like this :

<RadDiagram>

<Shapes>

<RadDiagramShape Type="Telerik.WinControls.UI.RadDiagramShape"

</Shapes>

</RadDiagram>

I don't know if it's possible to instanciate objects with their derived type like specified in the XML ?

Thanks in advance

Scrolling RadTextBox

Hello,

I'll try and explain what I'm after. I have a multiline RadTextBox, (takes about 7 lines of text). I dont want to show scroll bars as I start to type. When the text gets to the 8th line either via enter or wordwrap to make the vertical scroll bar appear.

I can do this with a RichTextbox but need to use a RadTextBox

Is this possible?

I have tried using the .lines property but that doesn't increment when using word wrap.

Any help much appreciated.

Displaying the distance between 2 shapes in connection content

Hello,

I would like to implement a custom connection content, depending on the size of the connection.

Basically, I would like to display the distance between the 2 Shapes that are linked by the connection.

I have tried to play with OnConnectionManipulationCompleted event, and I'm able to display that info at the creation of the connection, but it's never refreshed.

Do you know how if I can refresh that info while I'm dragging a shape ?

Thanks

Disallow field change

Hello,

I'm creating a DataFilter showing a premade expression and not allowing to Add or Remove other expressions or groups.

I'd like also to disable the possiblity to click on a field and change it, I want to keep them fixed.

I've seen the AllowEdit property, but it's too drastic, since it does not allow even to change the value to look for.

Where should I look?

Thank you!

DataFilter
