Hi,

This seems to work fine regardless of the current ZoomFactor:

private void Diagram_NodeDoubleClicked(object sender, MindFusion.Diagramming.Silverlight.NodeEventArgs e)
{
	diagram.ZoomToRect(e.Node.Bounds);
} 

What kind of coordinates are you setting for the zoom rectangle?

Stoyan

This is the code i am using,
[code]
ContainerNode selectedRectangle = activityDiagram.Items[activityDiagram.Items.Count - 1] as ContainerNode;
if (selectedRectangle != null)
{
     activityDiagram.ZoomToRect(selectedRectangle.Bounds);
     //Removes the selection rectangle drawn by the user to select the zoom area
    activityDiagram.Items.Remove(selectedRectangle);
}
[/code]

in the above code selectedRectangle is the node drawn by the user to zoom into.

When the selected rectangle is large, zoomtorect is working as expected. and when teh selected rectangle bounds are small(equal to the node bounds) it is failing to zoom into the selected region

Hello Stoyon,

There are many cases when the zoomtorect fails, below are the bounds and zoom factor at which it fails regularly.

Diagram bounds: {0,38,2580,851}
Selected Rectangle bounds: {849,750,154,98}
Diagram ZoomFactor : 100

How do we make the selected area to be centered in the view, i found in some fourm posts there is some method like BringIntoView(), is this still available. i am not able to find this method for the diagram control.

Hello Stoyon,

I've sent you an IM regarding steps to reproduce my issue.

This issue is not only reproducible zooming twice but it is also behaving same on zooming first time.


Please checkout the IM.
As this issue is a high priority one for us.


Thanks,

Hi Stoyo,

We have really customized our application a lot and will take much time to make a sample project which can reproduce our problem.
can you please send me your sample code so that i can verify where i am doing wrong in my code.

I've updated one of the samples provided by Mindfusion documentation to reproduce my problem.
Here you can find the http://docs.google.com/leaf?id=0B6zEK6RhNaOZMzUwOTI0NzctODUxMC00NmFiLTg0ZDktOWEx... updated code.

Steps to reproduce:
-> Run the applicaiton
-> Default diagram will be generated, now click on ZoomToRectangle Button provided
-> Draw a rectangle to create an area to zoom in
-> On Diagram MouseLeftButtonUp i have written code to zoom into the selected region

In this case it is not even zooming once to the selected region. Please have a look at this,
In the meanwhile i will look into the sample code provided by you.

Hello Stoyon,

Thanks for all your effort from your side... At last my issue has been fixed, problem was with our code....

If you observe in our application there is a zoomslider at the bottom right corner, which is causing the problem.
when we select regional zoom it was setting the slider value and our max slider value was 200, Once the slider value was set again the diagram zoomfactor was setting, resulting in a two way binding...


Once again.. thanks a lot for all your effort..
