Selection symbol for Graphics Overlay

VishnuB — Sun, 22 Jul 2018 13:16:07 GMT

Currently there is only one option to change the selection property of selected graphics in a GraphicsOverlay, and that is by changing the selection color. Instead of changing selection color, Is it possible to set a selection symbol for selected graphics (for eg: a square box around the selected graphics)

Hi Vishnu-

It is not possible at this time.

Vishnu-

What is your use case for wanting a selection symbol instead of just modifying the color?

You could just take the symbol geometry's envelope and draw that?

Hi Lucas,

Thank You for your response.

The MIL standard which i am following to develop the application strongly recommend to show a red rectangle (Military Symbology) around the selected point symbol. As a work around i had done this by creating a new graphicsLayer and display the rectangle symbol using picturemarkersymbol around the selected entity. If the selected entity is a moving object i need to update the geometry of the rectangle symbol along with the selected entity. It will be good if this feature gets implemented in the feature release.

Thank You.

Thanks Vishnu. Which MIL standard are you using?
