Actually I am using ArcGIS API for JavaScript 4.7 and i have a custom internal layer . I want to get name of place particular area when draw polyline the column name is (PLC_NAME) . How to achieve that ?
Suppose I draw a area through polyline. In this area there are places . Now I need to get name of these places .
you can find the using code in below i am using the TileLayer.

OK, you can resolve the queries on the client or on the server. Depends on your task what options you can pick on.
If you are going to use a spatial query, like the one you mention, and you will apply it on a FeatureLayer, you could solve it on the client. This is a good solution because you already have the features, you are seeing them. Here you have a question whis this situation, how-to-get-get-name-of-hospital-or-street-in-particular-area-when-draw-polyline.
Now, If you need to query something that might not be in your extent (you don't have the features) or you are not using a FeatureLayer, you probably will need to command the server to do this. But don't worry the library has several tools to work with, like QueryTask.
Here you have the same example of the answer link before but using QueryTask.

To close I leave you this link to the documentation that explains very well all the possibilities, pros and cons.
I am using arcgis js api.I have called all necessary esri class modules and all class name in order. I am using query task to add points to map as a graphic layer.I am getting error for graphic.I am not able to trace the error.

A couple of things. I don't see anywhere that you have called the function CoreMeasures. Also you might have an issue with the following code:
function CoreMeasures(title) {
var self = Ti.UI.createWindow({
title:.title,
backgroundColor:'white'
});
I noticed a dot before your title.
I am trying to open a new window by click a row in tableview in titanium.
this is my code,

backgroundColor:'#fff'
});
var dataArray = [{
title:'Sunday',
hasChild:true,
test:'detail'}];
for(var i=0;i<dataArray.length;i++){
dataArray[i].color = '#000';
dataArray[i].font = {fontWeight:'bold',fontSize:20};
}
var tableview=Ti.UI.createTableView({
data:dataArray
});
tableview.addEventListener('click',function(e){
if(e.rowData){
Ti.API.info(e.rowData.title);
var winEvent = Titanium.UI.createWindow({

winEvent.open({animation:true});

What to do to open detail.js window by clicking tableview row.
Thankyou.
Surendra, this is something similar to your problem. It opens a window while you clicks on each row.
Code is
var wndHome = Ti.UI.createWindow({
backgroundColor : 'white'
});
var tableView = Ti.UI.createTableView({
top : 0
});
var tabledata = [];
for(var i = 0 ; i < 10; i++){
var row = Ti.UI.createTableViewRow({
title : 'Title of window',
url : 'details.js'
});
tabledata.push(row);
}
tableView.data = tabledata;
wndHome.add(tableView);
wndHome.open();
tableView.addEventListener('click', function(e){
var wndNewWindow = Ti.UI.createWindow({
backgroundColor : '#999966',
url : e.rowData.url
});
wndNewWindow.open();
});
details.js file
var self = Ti.UI.currentWindow;
var label = Ti.UI.createLabel({
text:'Hai',
color:'#000'
});
self.add(label);
Here I've given the url to details.js. If you want to use different windows, then keep the file names in an array and while creating the tableViewRow, you can simply add the array element as the url(eg: fileArray = ['file1.js', 'file2.js','file3.js'];).
Try this and change your code as per your requirement.
im using for first time appcelerator for a Iphone app, im using a TableViewRow, when the window load all is fine, but if i want to refresh the window, the TableViewRow repeat the same data every time that i push refresh, so, i have 5 Categories, after refresh im having the same Categories repeting every time that im trying to refresh.

When you press the refresh button clear the tableData array and assign to table set data function before you fill your table again. So it will empty your table first and than fill new refreshed data.
Like this,
refreshBtn.addEventListener('click', function() {
tableData = [];
table.setData(tableData);
loadTutoriales();
});
