How can I retain custom position of label in WinForms Diagram?
How can I retain the custom position of the label while resizing the node?
We can retain the label's offset value using the SizeChanged event. While resizing a node, the SizeChanged event gets fired. Using the event, we can retain the label's position.
C#
// Adding Event Handler
((DocumentEventSink)diagram1.Model.EventSink).SizeChanged += new SizeChangedEventHandler(Form1_SizeChanged);
outerRect.Labels.Add(new Syncfusion.Windows.Forms.Diagram.Label());
outerRect.Labels[0].Text = "Rectangle";
outerRect.Labels[0].Position = Position.Custom;
outerRect.Labels[0].OffsetX = outerRect.Size.Width / 2;
outerRect.Labels[0].OffsetY = outerRect.Size.Height;
// Resizing
void Form1_SizeChanged(SizeChangedEventArgs evtArgs)
{
outerRect.Labels[0].OffsetX = outerRect.Size.Width / 2;
outerRect.Labels[0].OffsetY = outerRect.Size.Height;
}
VB
'' Adding Event Handler AddHandler (CType(diagram1.Model.EventSink, DocumentEventSink)).SizeChanged, AddressOf Form1_SizeChanged outerRect.Labels.Add(New Syncfusion.Windows.Forms.Diagram.Label()) outerRect.Labels(0).Text = "Rectangle" outerRect.Labels(0).Position = Position.Custom outerRect.Labels(0).OffsetX = outerRect.Size.Width / 2 outerRect.Labels(0).OffsetY = outerRect.Size.Height '' Resizing Private Sub Form1_SizeChanged(ByVal evtArgs As SizeChangedEventArgs) outerRect.Labels(0).OffsetX = outerRect.Size.Width / 2 outerRect.Labels(0).OffsetY = outerRect.Size.Height End Sub
