How to use the property grid in the WPF Diagram (SfDiagram)?
1 min read
The PropertyGrid control can be used to show the properties of the selected object and able to change the values dynamically. The properties values will be updated dynamically based on the selected objects using the events of the WPF Diagram (SfDiagram) control.
C#
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
SfDiagram diagram = new SfDiagram();
(diagram.Info as IGraphInfo).ItemSelectedEvent += MainWindow_ItemSelectedEvent;
(diagram.Info as IGraphInfo).AnnotationChanged += MainWindow_AnnotationChanged;
}
private void MainWindow_AnnotationChanged(object sender, ChangeEventArgs<object, AnnotationChangedEventArgs> args)
{
if (args.Item is IAnnotation)
{
propertyGrid1.SelectedObject = args.Item;
}
}
void MainWindow_ItemSelectedEvent(object sender, DiagramEventArgs args)
{
if (args.Item is INode)
{
propertyGrid1.SelectedObject = args.Item;
}
else if (args.Item is IConnector)
{
propertyGrid1.SelectedObject = args.Item;
}
}
}
