How to update the ShapeStyle of the selected node at runtime in WPF Diagram (SfDiagram) ?

In the WPF Diagram, you can update the ShapeStyle of the selected node at runtime by assigning the new style to the node’s ShapeStyle property. Since you cannot directly assign a style, use the style’s key to accomplish this. We have provided the code example for how to achieve this.

Code Snippet

private void Button_Click(object sender, RoutedEventArgs e)
{
    NodeViewModel selectedNode;

    if (diagram.SelectedItems is ISelector selector && selector.Nodes is IEnumerable<object> selectedNodes)
    {
        selectedNode = selectedNodes.FirstOrDefault() as NodeViewModel;

        if (selectedNode != null)
        {
            selectedNode.ShapeStyle = this.Resources["ShapeStyle"] as Style;
        }
    }
}
