Preserving data on Undo

[Deepak Shakya]

Hi,

Could someone please tell me how I can preserve the shape content (data) when I undo the "delete".

Here is my scenario:

• Diagram's GraphSource is bound to a collection derived from ObservableGraphSourceBase<ITreatmentNode,TreatmentLink>
• The node content is set via DataTemplate and also has EditTemplate
• I drop the shape and edit the values
• I then delete the shape by mistake
• I undo it (Ctrl +z)
• The shape appears but the data is lost. It has the default values that was there when I dropped the shape.

Is there a way to control this?

Hi Deepak,
Could you please send us some code snippets or a sample project because I wasn't able to reproduce you issue? I've attached the sample project that I used for testing so you could examine it and see if it helps you.
If you have further questions please feel free to ask.

Kind regards,

Hello Naga,

Note that this is the RadDiagram for Silverlight section of the forum and the previous communication is related to the Silverlight control. This is why I would ask you to post your question in the Kendo forum or open a new support ticket with its product set to the Kendo diagram.
