Hey guys, I've found a couple threads here that were helpful, but there must be some difference in my situation as I am unable to get them to work properly. I have a page with a JavaScript kendoGrid using an ODATA service as its dataSource. The dataSource primary key is "id" and on document.ready I want to page to, and select, the matching Row based on the data field "Id" and the QueryString parameter.

The below code all functions correctly as far as the alert(caseId) in the document.ready function. After that nothing happens. Can anyone see what I'm doing wrong?

Also, I have tried replacing caseId in the dataSource.get(caseId) with a hard coded Id but it did not work...

Hi Chris,

As the data is loaded from remote service, you will not be able to access it before it is loaded, which is what is happening in the code you have pasted. Here, I have prepared a small test page which demonstrates how to handle the scenario in question. Basically the code should look similar to the following:

$(document).ready(function () {

var el = $("#grid"),

grid = el.data("kendoGrid"),

dataSource = grid.dataSource;

// we should wait till the data is fetch in order to find the model by its id

$.when(dataSource.fetch()).done(function() {

var caseId = getParameterByName('id');

if (caseId === "") {

return;

}

var model = dataSource.get(parseInt(caseId, 10)),

index = dataSource.indexOf(model);

// use the dataBound event to select the row

grid.one("dataBound", function() {

// the row has an uid attribute set

var row = this.items().filter("[data-uid=" + model.uid + "]");

grid.select(row);

});

dataSource.page(Math.floor(index/dataSource.pageSize()) + 1);

});
