Question

I have created a kendo.data.dataSource with success, and I am able to bind it to the KendoUI Grid on my page.

But when I try to dataSource.insert(0, [a : "b"]); it removes the data that was there previously.

My example code follows:

var tempSource = new kendo.data.DataSource({
     data: [{"ID":1,"Name":"Cliente 1","NameID":"1 - Cliente 1"},{"ID":2,"Name":"Cliente 2","NameID":"2 - Cliente 2"}]
});

This is how I’m binding to the grid:

$("#association-grid").kendoGrid({
height: 99,
columns:
[
    {
        field: "ID",
        title: "ID"
    },
    {
        field: "Name",
        title: "Name"
    },
    {
        field: "NameID",
        title: "NameID"
    }
],

dataSource: tempSource
});

This is how I add a new item:

tempSource.insert(0, { ID: "John Smith", Name: "Product Description", NameID: "123 1st Street" });

If I perform the add before binding the data to the Grid, I lose the first two items that were originally on the dataSource object.

In summary:
I have a pre-created dataSource binded to a Grid. I want to be able to add a new item to the dataSource, and then refresh the Grid so that the new item appears.

Thanks,

VRC
