Scope of setting RadGridLocalizationProvider

What is the scope of setting RadGridLocalizationProvider please?

When setting it, it doesn't seem to be assigned to anything eg a particular window. So I'm a bit confused whether it should be set once on startup or if it should be set per form.

On the surface the function "CurrentProvider" appears to be setting.a static variable somewhere, so does the function add the new instance to a list? or does it override a single instance and need resetting after a child form is disposed?

Sorry if this seems like a dumb question.

public class GeneralRadGridLocalizationProvider : RadGridLocalizationProvider

{

public override string GetLocalizedString(string id)

{

switch (id)

{

case RadGridStringId.ConditionalFormattingPleaseSetValidCellValue: return GuiResources.Please_set_a_valid_cell_value;

//foo bar the remaining ids

case RadGridStringId.ExpressionFormNotButton: return string.Empty; //if empty, default button image is used

}

return string.Empty;

}

}// class

public function FooBar()

{

RadGridLocalizationProvider.CurrentProvider = new GeneralRadGridLocalizationProvider();

}

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
