Rajni,

   This should not be difficult for you to figure out. Right now you have one or more view.on click listener functions. Just add a view on dbl click listener and then add the view.hit test logic there (just like you have in the on click event handler).

Hi Sir,

I tried your way, in console, i get that exact polygon clicked, but i could not able to remove that graphics from map

with graphicslayer.remove method

Am i missing something??

Do i have to use other function.

    view.on("double-click", function(event){
              view.hitTest(event).then(function(response) {
                var results = response.results;
               results.forEach(function(result) {
                if(result.graphic.geometry.type==='polygon'&&result.graphic.layer === sketchViewModel.layer && result.graphic.attributes && result.graphic.attributes.newDevelopment){
                    console.log(result.graphic);  
                    graphicslayer.remove(result.graphic);
                  }
                });
              });
           });

I tried 2 methods, both don't work out, while console return me the exact that polygon that i clicked, but still stucked to delete it.

I want to delete polygons of graphics layer only.

view.on("double-click", function(event){
              view.hitTest(event).then(function(response) {
                var results = response.results;
               results.forEach(function(result) {
                if(result.graphic.geometry.type==='polygon'&&result.graphic.layer === sketchViewModel.layer && result.graphic.attributes && result.graphic.attributes.newDevelopment){
                    console.log(result.graphic);  
                   /*graphicslayer.remove(result.graphic);
                  view.graphics.remove(result.graphic);*/
                  }
                });
              });
           });

Rajni,

   As a developer you need to figure out if the fact that it is not working in your code is due to any of your other code. So make a simple NEW app that only have the double click delete event listener to test if it work for you there.

/*graphicslayer.remove(result.graphic);
                  view.graphics.remove(result.graphic);*/

While my console in this code return my clicked polygon as graphic

I don't doubt that you are getting into the listener. But my reply still stands you need to test an app that is devoid of all your other listener events to rule out code overriding each other.

Rajni,

   No there is no specific event for right click. You have to check the regular click events 

https://developers.arcgis.com/javascript/latest/api-reference/esri-views-MapView.html#event-click 

Button property for the right click.
