Hi there,

i am searching for a way to mask the diagram while the different nodes and links are loaded and arranged for i don't want the user to see every step of this process.

Thank you in advance
Lutz

Hi Lutz,

If you mean this for applet mode, call the suspendRepaint() and resumeRepaint() methods of DiagramView. You can see them used in the onGotNames function in the OrgBrowser example.

I hope that helps,
Stoyan

Hi Stoyan,

i'm adding a MindFusion.Diagramming.Wpf.DiagramView object containing the diagram to a System.Windows.Controls.DockPanel and in that case there are no such methods defined in DiagramView.

It would be very kind, if you could give me a hint for this case.

Thx
Lutz

Oh, I didn't notice this is for the WPF control. Are you adding the items from a timer?

No.

I have tested the Opacity property of UIElement for my purpose, but it didn't work.

Next i have tried it with two views using InactiveOpacity = 0.0 and activating one of them after loading, but it didn't work.

I have never seen the diagram appearance being updated while elements are added from a loop; could you post you xaml and C# item-loading code here? In any case, you could add the Diagram to the WPF visual tree only after all items have been added to it.
