NullRef exception

I was working with the symbols class and was using your code --> +++++++++++++++++++++++++++ this.nameLbl = this.AddLabel("", BoxPosition.Center); this.nameLbl.OffsetY = -20; this.nameLbl.FontStyle.Name = "Verdana"; this.nameLbl.FontStyle.Style = System.Drawing.FontStyle.Bold; this.nameLbl.BackgroundStyle.Color = System.Drawing.Color.Transparent; this.nameLbl.ReadOnly = true; +++++++++++++++++++++++++++++++++++++++++++++ Everytime it gets to this point it gives me a Unhandled exception of type "System.NullReferenceException" occured in syncfusion.diagram.base.dll Object reference not set to an instance of an object. Can someone help me with this issue?
