Kendo Grid not showing data with proper json being returned - kendo-ui

Question

My kendo grid is not showing data after successfully calling a web method and seeing data being returned in the ajax request.
$(document).ready(function () {
var filterSource = new kendo.data.DataSource({
transport: {
read: function (options) {
$.ajax({
type: "GET",
url: "DoJo.aspx/GetProjects",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (msg) {
// msg.d has the json data
}
});
}
},
schema: {
model: {
fields: {
ProjNum: {type: "string"},
Stat: {type: "string"}
}
},
data: "d"
},
change: function (e) {
// e.items is empty
}
});
$("#grid").kendoGrid({
dataSource: filterSource,
columns: [
{
field: "ProjNum", title: "Project Number", width: "130px", filterable: {
multi: true,
dataSource: filterSource
}
},
{
field: "Stat", title: "Status", filterable: {
multi: true,
dataSource: filterSource
}
}
]
});
})
The JSON below is in an array format.
[{"ProjNum":"12345","Stat":null,"ProjTitle":"Test Title","ClientName":"Test Client","ClientContactName":"Test Name","ClientFacilityLocation":"Test Location","SourceOfContact":"Test Contact","ProjManager":"Test Manager","Department":"Test Department"}]
Why is change callback returning an empty e.items? If I remove data: "d" it returns e.Items with the JSON data.

Answer 1

When you set dataSource.transport.read to a function and invoke the ajax call yourself, you need to pass the result (or error) back into the dataSource, like so:
var filterSource = new kendo.data.DataSource({
transport: {
read: function (options) {
$.ajax({
type: "GET",
url: "DoJo.aspx/GetProjects",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (msg) {
// msg.d has the json data
// notify the data source that the request succeeded
options.success(msg);
},
error: function(msg) {
// notify the data source that the request failed
options.error(msg);
}
});
}
},
schema: {
model: {
fields: {
ProjNum: { type: "string" },
Stat: { type: "string" }
}
},
data: "d"
},
change: function (e) {
// e.items is empty
}
});
