Customize Polygon tool

[John Previn Kumar]

Is it possible to create a polygon drawing tool which draws polygons with transparent background and blue border line?
The vertices of the polygon should be visible and editable.

Hi Bose,

Thanks for your interest in Syncfusion products.

Yes, it is possible to create polygon tool which draws polygons with transparent background and blue border line. We suggest you to create the ‘CustomPolygonTool’ and ‘CustomPolygonNode’ classes which inherit from ‘PolygonTool’ and ‘PolygonNode’ Classes respectively to achieve your requirement.

For your convenience, we have created a simple sample to demonstrate this.
Please try the below sample and let us know if you have any queries.

Thanks. How do I add these polygons drawn by the polygon tool to a particular layer?

Hi Bose,

Thanks for the update.

We suggest you to set the Layer’s ‘Enabled’ property to ‘true’ and add that layer to the Diagram.Model’s ActiveLayer’s collection. If a node is added to the Diagram.Model, then it will automatically added to that Activelayer.

Here is the Code snippet:
[C#]
Layer layer1 = new Layer();
layer1.Visible = true;
layer1.Enabled = true;
this.diagram1.Model.ActiveLayers.Add(layer1);

For more information, please see the below online documentation UG link:

For your convenience, we have modified the sample to achieve your reuirement.
