Hi GTec,
Thanks for your interest in Syncfusion products.
IMouseEventReceiver interface is no longer valid in v5.2. You can use ProcessMouseDown, ProcessMouseMove and ProcessMouseUp methods for firing events in the customtool.
You have to derive a Tool class to create a custom tool. After creating a custom tool you have to register it in Diagram Controller. Please refer to the following code snippet
[C#]
//To activate the LineTool in MainForm.cs
MyLineTool linetool = new MyLineTool(this.diagram1.Controller);
this.diagram1.Controller.RegisterTool(linetool);
this.diagram1.Controller.ActivateTool(linetool);
I have attached the sample that demonstrates this completely. You can download the sample from the following page.
