Multiple selection in custom visual

Hi everyone.

 

I wanted to know, how to do multple selection using pressed CTRL button and mouse click, instead of mouse click. I set

this.selectionManager.select(d.identity, true), and it selects multiple data, but just by mouse click. How to alter it for identification of CTRL button pressed?

    Hello ysapiyev,

     

    You should use something like this (event documentation):

     

    // event is a mouse event

const isCtrlKeyPressed = event.ctrlKey;

this.selectionManager.select(d.identity, isCtrlKeyPressed);

      Hello v-viig,

       

      So ,as I understood, it should look like this, right?

      var event =  <Event>d3.event;
const isCtrlKeyPressed =event.ctrlKey;

this.selectionManager.select(d.identity, isCtrlKeyPressed);

      However, it shows me that there is no property ctrlKey in event. I googled, and it gives me similar solution as yours. What can be wrong?

       

      Regards,

        That code snippet looks good.

        Can you share the whole source code for debugging?
