Uncaught Each data element must implement a unique 'id' property

[ghost]

When I bind json data to slick using dataview it shows above error what is the problem here can any one help me

Did you look at the source of the examples ? Your JSON must have an 'id' property, as the error says. It's not hard. But you'd need to post a sample of your data here to get any assistance at all.

Here is my json sample [{ "empid": 1, "fname": "John", "lname": "Doe", "email": "jdoe@gmail.com", "sdate": "4/3/2012" }, { "empid": 2, "fname": "Stuart", "lname": "Motzart", "email": "jdoe@gmail.com", "sdate": "4/3/2012" },]

Thanks for giving the reply and the thing is if Iam using ajax call directly it displays nicely with same service url

Just rename "empid" into "id" and it will work. It is what "must implement a unique 'id' property" means.

great it works but grid is displaying data is not populated

[ghost]

this is my code what's the problem here and onrowschanged and onrowscountchanged functions are nott fired dataView = Slick.Data.DataView(); dataView.beginUpdate(); dataView.setItems(obj); dataView.endUpdate();

                         grid = new Slick.Grid("#teamGrid", dataView, columns, options);
                       dataView.onRowsChanged.subscribe(function (e, args) {
                             grid.invalidateRows(args.rows);
                             grid.render();
                         });
                         dataView.onRowCountChanged.subscribe(function (e, args) {
                             grid.updateRowCount();
                             grid.render();
                         });

Firstly, try to compare your code to one of the examples in repository. If still nothing seems wrong, make a jsfiddle http://jsfiddle.net/ example - it would be much easier to help you after that.

You do not need to rename empid to id. When you set the items in setItems function, you can specify the id property.

setItems(items, "empid")

This is the definition of setItems function.

function setItems(data, objectIdProperty) {
  if (objectIdProperty !== undefined) {
    idProperty = objectIdProperty;
  }
  items = filteredItems = data;
  idxById = {};
  updateIdxById();
  ensureIdUniqueness();
  refresh();
}

If these two functions are not executing means problem with json data?

[ghost]

dataView.onRowCountChanged.subscribe(function (e, args) { grid.updateRowCount(); alert("hi"); grid.render(); });

dataView.onRowsChanged.subscribe(function (e, args) { grid.invalidateRows(args.rows); alert("bye"); grid.render(); });
