  1. POPopulating a Kendo UI Combobox with big JSON string
    text
    copied!<p>I have a MVC3 ASP.NET Project in which I am using jQuery and KendoUI for the view. I have defined the combobox, a dataSource for it and I am getting results from the controller with the JSON string in correct format within the dataSource.</p> <p>The data returned as JSON string is about 500kb and the combobox is not showing anything. It just shows the loading icon in the right side of it. I think the large amount of data really is a problem here...</p> <p>Can anyone help?</p> <p>Bellow is a snippet of my code:</p> <p><code>&lt;input id="kendoCboClienti" /&gt;</code></p> <pre><code>&lt;script type="text/javascript"&gt; $(document).ready(function () { clientiDS = new kendo.data.DataSource({ transport: { read: { url: "/Clienti/", dataType: "json" } }, schema: { model: { fields: { id: { type: "string" }, ragioneSociale: { type: "string" } } } } }); $("#kendoCboClienti").kendoComboBox({ placeholder: "Sceglie il cliente", dataTextField: "RAGIONE_SOCIALE", dataValueField: "ID", dataSource: clientiDS }); }); &lt;/script&gt; </code></pre> <p>And the JSON string look similar to this:</p> <pre><code>[ {ID:429,RAGIONE_SOCIALE:"AUTOTRASP.PORETTO G."}, {ID:430,RAGIONE_SOCIALE:"P.G. JOHNNY IMPORT EXPORT"}, {ID:431,RAGIONE_SOCIALE:"CONFARTIGIANATO TREVISO"}, ..... ] </code></pre> <p>In jsFiddle works, but it is very very slow, unresponsive and the browser crashes sometimes for that amount of data.</p> <p>Thanks!</p> <p><strong>Edit 1:</strong> I've modified the amount of data sent to the dataSource (only 10 records) and still doesn't work. Maybe it's a problem with the dataSource?</p>

An individual column

Larger individual text columns get their own page to allow for proper reading.
