Zoom to a Node inside a diagram

[Administrator]

Is it possible to zoom into a specific child node of a group control on a diagram?

Say we have a group control with few children. When user selects a child node I want to zoom-in that particular node and fit in to view.


Thanks,

Hi Babu ,

Thanks for your interest in Syncfusion products.

Please refer to the attached sample that demonstrates to zoom in and zoomout the selected child nodes of a group.

http://websamples.syncfusion.com/samples/Diagram.Windows/F74031/main.htm

In this sample you can select the Ellipse or TextNode and you can Zoom-In and Zoom-Out the child nodes by using the corresponding buttons.

Please let me know if you have any questions.

Thanks,

Thank You Nagaraj.

But, I can't see that the child of a Grop control gets zoom-in and zoom-out (eg, m_innerEllipse of your MySymbol class) in your sample;instead the whole group box's zoom property is getting updated.

If we want to zoom-in a standard Node(say Ellipse, Rectangle etc), do we need to derive new classes from each of these Node type (say MyEllipse, MyRectange ect) and then update the protected BoundsInfo property? Does this sounds weird?

Thanks,
Babu

Hi Babu ,

I have modified the sample and attached here.

In this sample you can select the Ellipse or TextNode and you can zoom in and zoom out the child nodes.

Please refer to it and let me know if this helps.

Requirement is exactly like in original post here
