GoXam for WPF v3
ValidLayout Property (DiagramLayout)
Northwoods.GoXam.Layout Namespace > DiagramLayout Class : ValidLayout Property
Gets or sets whether this layout is valid; if not, the Northwoods.GoXam.LayoutManager will call DoLayout sometime in order to make sure the layout is valid.
Syntax
[Browsable(false)]
[DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
public bool ValidLayout {get; set;}
Remarks
This property simply holds the validity state -- changing the value does not request the performance of the layout any time soon.
