Hello, I'm attempting to export to pdf from javascript and get the following error from the api. Does anyone know what this error means and if there's anything I can do to get it working?

Hi Chris, 

We are able to reproduce the problem with the given code example. ejGrid exports the Grid based on the model values given in the plugin. If the columns present in the Grid is different or not available in the datasource bound to the export method, it will not export the Grid and throws an error. The following Exporting Service link is prepared based on the columns present in the demo showcased next link and it is exclusively only for our JS sample browser sample. 

ejGrid’s Exporting action needs server-side operation and so you have to maintain the exporting action at server-side and export the columns and dataSource bound to the Grid. In the following example, we have C# has the backend for handling the exporting action. Refer to the following code example.  

<div id="Grid"></div> 
<script type="text/javascript"> 
    $(function () { 
        var json = @Html.Raw(Json.Encode(ViewBag.dataSource)); 
            dataSource: json, 
            allowPaging: true, 
            toolbarSettings: { showToolbar: true, toolbarItems: [ej.Grid.ToolBarItems.ExcelExport] }, 
            . . . . . 
              . . . . 
        public void ExportToExcel(string GridModel) //Server-side 
            ExcelExport exp = new ExcelExport(); 
            var DataSource = OrderRepository.GetAllRecords().Take(50).ToList(); 
            DataOperations operation = new DataOperations(); 
            GridProperties obj = ConvertGridObject(GridModel); 
            exp.Export(obj, DataSource, "Export.xlsx", ExcelVersion.Excel2010, false, false, "flat-saffron"); 

You have to refer the following assemblies in your project to export to excel.  


Refer to the following Help Document for the server-side configuration of exporting Grid. 

We have prepared a sample that can be downloaded from the following location.
