    I am getting a unexpected end of json error when using the control with a file size of 31M. When I decrease the size of the to around 4 MB, it works without any error. I have already increased the my httpRuntime maxRequestLength to 2097151, or 2G.

    Is there a maximum file size for the control?

    Here is my code

    <div style="padding-left:15px; padding-right:15px; padding-top:5px; height:100%">
        <div id='jqxWidget' style=" font-size: 13px; font-family: Verdana;">
            <div style='margin: 10px;'>
                <h7>Upload Test Scripts</h7>
            <p />
            <div style='margin: 10px;'>
                <div id="jqxFileUpload"></div>            
    <script type="text/javascript">
        var testScriptID = "";
        var moduleName = "";
        var featureName = "";
        var tagName = "";
        var step = "";
        var newTags = [];
        var moduleFeatures = [];
        $(document).ready(function () {
            $("#jqxWidget").jqxPanel({ width: '100%', height: 875 });
                width: '25%',
                uploadUrl: '@Url.Action("Upload", "QARep")',
                fileInputName: 'filesToUpload',
                localization: {
                    browseButton: 'Select File'
                theme: 'energyblue'
            $("#jqxFileUpload").on("uploadEnd", function (event) {
                var args = event.args;
                var response = args.response.split(">");
                var json = response[1].split("<");
                var result = JSON.parse(json[0]);
                showNotification(result.State, result.Message);
                if (result.Data !== null) {
                    var url = '@Url.Action("Detail", "TestScript")/' + result.Data;
                    location.href = url;


    Hello Neil,

    No, there is no maximum file size for the control. There are no restriction by size for jqxFileUpload.

    Let us know if you need further assistance.

    Best Regards,
