BringIntoView

Hi,

I can't seem to get BringIntoView to work - if the node I want to bring into view is way off to the right the diagram does not display it.

I'm sure this is a problem with my code, which is;

diagram.BringIntoView(node.Bounds);

Any ideas?
Thanks in advance.

Hi,

Are you using the official 1.0 release? That method wasn't implemented correctly there. It should work in this version:
https://www.mindfusion.eu/_beta/wpfdiag101pre.zip

as long as Diagram.Bounds contains Node.Bounds and the Diagram object is inside a ScrollViewer.

I hope that helps,
Stoyan

Hi,

I've downloaded this to no avail - it still won't display nodes off screen.

The diagram is contained in a scroll viewer, and diagram.Bounds.Contains(node.Bounds) returns true.

Also this download has a side affect - the grab handles on the nodes are suddenly about 10 times larger than normal.

Hi,

Now the default MeasureUnit is WpfPoint, and we have changed all size-related properties to match it. You will have to scale down the AdjustmentHandlesSize property value to fix the handles size.

Regarding BringIntoView, that was my mistake - we have recently implemented a ZoomToRect method, and I confused it with BringIntoView when you mentioned it. The BringIntoView(Rect) method you are using is implemented by the base FrameworkElement class, but apparently it does not work correctly for Diagram. We'll override it or implement a BringIntoView(DiagramItem) method (which is available in our Windows Forms control).
