Hi Friends, am trying to display the results in datagrid after performing query tasks on layers. Anyone help me with this..

I found some samples but it is in 3.25.... and in that one the table is visible from starting.. I think we can get it when we perform query..

RAJ,

   So you just need to combine the two samples like this then:

Hello Robert, I checked this sample. Its helpful but in this sample user use polygon to perform query. I have to use only simple query task.. 

like 

if(wlayer.value === 'city'){
qTask.execute(params)
.then(getResults)
.catch(promiseRejected);
}else if(wlayer.value === 'road'){
qTask2.execute(params)
.then(getResults)
.catch(promiseRejected);

Right now results only popups on the map one by one..I am looking to get query task results as data grid below the map, after user perform a query. am using same code you already help me previously...

Thanks for the Solution...It was exactly am looking for but I have one question can we highlight result we select from the query result..

i tried to using this 

  •  view = new MapView({
    container: "viewDiv",
    map: map,
    highlightOptions: {
    color: "red",
    fillOpacity: 0.4
    }
    });

how can we highlight the selected results on map and grid at the same time..

sample refer

The results are already added to the map as graphics so I am not sure what you mean.

Yes results are added perfectly as am trying.. Thanks a lot for that.. but you ask me to refer one sample previously 

https://developers.arcgis.com/javascript/latest/sample-code/sandbox/index.html?sample=highlight-feat...

In this sample after performing query task, when we click on any record in grid it highlights that specific record on map with specific color.. I have already attach an image for about my question..

i tried this 

highlightOptions: {
color: "red",
fillOpacity: 0.4
}

how can I do that in the code which you just provide to me...??

It is as simple as adding another graphic after you query for the ObjectId of the row you clicked on. If you need more help with that code then you should start a new question.
