Hi,
I have set the width and height of the diagram control. Now can you please help in letting me know how to restrict the Diagram shape that I now dropped in the diagram area to move within this constraint area only. Please suggest something.
Thanks in advance.

Hi Yogendra,
I am happy to inform you that the RadDiagram exposes services that can be used to achieve your goal. You can find ready to run project in our XAML SDK where we demonstrated how you can implement custom service.
Please take a look at the project and let us know if you need any further assistance.

Thanks your reply back.
Your solution is working with mouse but i can change the left, top, width and height from numeric up down button, and values are bounded with property. Code is here:-
when i changing width, height, left and top from numeric updown button, shape does not restrict within constraint area.
Thanks in advanced.

Hi Yogendra,
You are right that the provided custom service is working when the the shapes are being moved using the mouse. In order to implement such restriction whenever the Position (or any other) property is being changed you can check the value of the property exposed by your ViewModel before changing it.
For example lets take the Width property in your ViewModel. Lets say that it should not be greater than 90 pixels. Hence, you can change it only when the Value in the setter of that property is lower than 90, if equal or greater you can set it to 90.
In other words - when using MVVM approach you can implement custom logic in your ViewModel to verify that the properties (Position, Height, Width...) are in the desired range.
Please give this approach a try and let us know if you have any other questions.
