Show SettingsPane automatically when new raddiagramitem is dropped into diagram

[Fredrik]

When draging a toolboxitem from the toolbox gallery into the diagram is it possible to automatically open the SettingsPane ?

I have the following scenario: The user drags components from the toolbox into the diagram , the components have a few mandatory properties that needs to be set in its business object. My strategy is to put a form for the input of these properties in the SettingsPane and have this open whenever a new component is dropped into the diagram.

Hello Fredrik,

You can use the Drop event handler of the RadDiagram and in it set the IsActive property of the SettingsPane to true in Dispatcher.BeginInvoke body.

You can check this approach implemented in the attached project for your convenience.

Thank you that works fine.

I found a small bugg in your code (it is also present in your examples online).
in Example.xaml.cs add

Using System.Globalization

and in DefaultSerializationService_ItemSerializing
Add CultureInfo.Invariant culture as a parameter to the Geometry.ToString method like so
e.SerializationInfo["MyGeometry"] = (e.Entity as RadDiagramShape).Geometry.ToString(CultureInfo.InvariantCulture);

Otherwise it throws an exception when you drop figures into the diagram. I am on a swedish Win 7 installation i am guessing this is the cause.
