var dataSource = new kendo.data.TreeListDataSource({
transport: {
read: {
url: "https://demos.telerik.com/kendo-ui/service/EmployeeDirectory",
dataType: "jsonp"
}
}
});
We have a defined url here so the data is requested from this single URL and stored.
In my use-case, I need to make 3 sequential server calls before I get the actual data.
That is why I need to intercept the read function of transport where I can make all the necessary backend calls and combine the results to move forward.
