I have a visualization layer bound to an observable collection of MapShapeData. There is a LineData in it whose initial points are Location.Empty. As I change Point1 and Point2, the line is correctly updated on the map. When I change Point1 and Point2 back to Location.Empty, the line stays on the map. I am expecting it to disappear.

This was the only simliar thread I saw:

Disable auto resize in RadDiagramContainerShape

HI there,

I am using RadDiagram, where I will have two container shapes (RadDiagramContainerShape) Front and Rear. User will choose a device and drop it into the front/rear block, so a diagram shape will be created and added into front/rear block. But once I added, the parent container shape resized even I added a shape with same width of parent.

How to disable the auto resizing of parent container shape.

Regards,
Jawahar

Adding mailmerge field at caret position from viewmodel.

In code-behind it is easy to insert a merge field:

this.radRichTextBox.InsertField(new Telerik.Windows.Documents.Model.MergeField() { PropertyPath = "SomePath" });

Is it possible, from the viewmodel, to the same thing?

Limit max number of items

Hello,

I was wondering if there's a simple way to limit at max 6 items the number of items present inside a LayoutControl? I've added a control inside my ViewModel and I avoid adding more if the Count reaches 6 but the whole space is not occupied

Thanks in advance

Bar series with Point series in one cartesian chart?

Hi,

I am having problems displaying Histogram(bar series) with Points(point series) within them in a CartesianChart in WPF.

If I declare only one single Horizontal axis(Categorical) for both the series, then the series are appearing one after another horizontally.

If I declare two separate axis(categorical) for both, then the scales arent getting adjusted equally.

I would want to achieve such that either both share a single Horizontal axis and both series are drawn overlapping or

let both series have two separate axis and their scale is equvivalent.

How do I achieve this?
