I am having a problem creating a dropdownlist inside of a grid cell. I have seen the docs and some other posts but I can't seem to get it to work.  Any insight to what I am doing wrong?

            dataSource: {
                data: self.MultipleUploadDetails,
            pageable: false,
            selectable: false,
            refresh: false,
            resizable: true,
            reorderable: true,
            noRecords: { template: "<div class='k-grid-norecords-template' style='margin:0 auto;position:static;'>No Files Uploaded</div>" },
            sortable: {
                mode: "multiple",
                allowUnsort: true
            columns: [
                    headerTemplate: "<div class='oir-actions-header'>Actions</div>",
                    title: "Actions",
                    width: 50,
                    template: '<a class="oir-exp-inv-pay-delete" href="\\#" data-uid="#:Uid#" title="Click to delete the file"><i class="fa fa-trash-o fa-fw fa-lg oir-fa-action"></i></a>',
                    attributes: { style: "text-align: center" },
                    filterable: false,
                    sortable: false
                { field: "FileName", title: "Name", width: 150, sortable: true },
                { field: "FileSize", title: "Size", width: 150, sortable: true },
                { field: "Id", title: "Document Type", width: 225,editor: docTypeDropDownEditor, template: "#=DocumentType.Name#" },
                { field: "IsConf", title: "Confidential", template: "<input type=\"checkbox\" />", width: 40, sortable: true, headerAttributes: { style: "text-align:center" }, attributes: { style: "text-align:center;" }},
                { field: "IsTs", title: "Trade Secret", template: "<input type=\"checkbox\" />", width: 40, sortable: true, headerAttributes: { style: "text-align:center" }, attributes: { style: "text-align:center;" }},
        function docTypeDropDownEditor(container, options) {
            $('<input name="' + options.field + '" data-value-primitive="true"/>')
                    autoBind: false,
                    dataTextField: "Name",
                    dataValueField: "Id",
                    dataSource: { data: self.DocumentTypes},

I am trying to bind to knockout sources, I know the sources are populated.

Each row should have a dropdown to select the document type, the selected Id will ultimately be passed in to the controller.

Hello, Jed,

Thank you for the provided code snippet. 

There are several changes that are needed in order for the example to work as expected.

1. I can't see the editable option for the Grid.

2. From the template for the Id field, I can see that you wish to bind the column to an object. In that case, the Id field should also be an object and not a number. As I do not know what data is passed to the Grid, I thought I would mention it.

I have prepared a small Dojo example with the provided code snippet for reference. Let me know if you have any questions.
