More complex geometry from code

Hi!

We need to make a complex custom shape (please see attached png). It is composed of many different geometries and brushes. Plus, we have to draw it dynamically from code because it should be drawn according to some properties (nb of floors, number of Windows, etc...), so we c'ant use a xaml to describe the shape.

In our current home made diagram control, shapes derive from visualdrawing and we use the drawingcontext in conjunction with GeometryDrawing object.

Now, we are evaluating Telerik diagram control. Would this be possible? How would you achieve this ?

Any infos appreciated, thanks !

Row Details Editing

Hello,

I have GridView that has a RowDetailsTemplate specified.

I am trying to figure out how to force the row in a GridView into Edit Mode when the user is editing a property that is displayed in the Row Details template of that row. The GridView properly goes into Edit Mode when I edit a cell in the row, but not when I am in the Row Details.

Any help is appreciated.

Thanks.

Set position of Timeline on Gantt to a specific date

Is there a way to set the position of the timeline on the gantt to a specific date?

For example, if the VisibleRange is set to:

this.VisibleRange = new DateRange(this.today.AddYears(-1), this.today.AddYears(1));

On a button click, I want to be able to position the timeline to DateTime.Today.

Anyone have any suggestions?

RadGridView does not allow updates to source objects from non-ui thread

Hello,

I'm attempting to update a property of an object in a collection that is being shown by RadGridView. The update is being done by a background (non-UI) thread. Normally, this isn't a problem - the WPF binding takes care of shifting to the UI thread to update the control.

However, RadGridView does not seem to follow this pattern.

I've created an example project to illustrate. Currently, the RadGridView is commented out, and a DataGrid is showing the collection. If we click the button that updates the source objects property on a background thread, then it works fine.

If we uncomment the RadGridView line (so we now have a datagrid and a radgridview showing the same collection), then updating the object property causes a "The calling thread cannot access this object because a different thread owns it" exception.

Is it possible to get RadGridView to behave in the same way as DataGrid in this case?

Thanks,
James.

[EDIT - I've realised I should submit a support ticket so I can attach the project, sorry]

MVVM Connection Issue

I am trying to do MVVM with the diagram framework. I modified the MVVM example in the Telerik\xaml-sdk on github.

I am getting a crash when doing the following. I create connector between a shape inside a
container with shape outside the container. Then I drag the shape outside the container into the container.

Then I immediately get this exception with this error message:
{"Unable to cast object of type 'Telerik.Windows.Controls.RadDiagramConnection' to type 'Telerik.Windows.Controls.Diagrams.Extensions.ViewModels.NodeViewModelBase'."}

Is this a known bug? Is there a way to do MVVM with diagram when having connectors and containers?
