Progress® Kendo UI® Spreadsheet for jQuery

Description

I want to show the editor to the side of the selected Spreadsheet cell and make it disappear when the user clicks outside the popup. Can I use the Spreadsheet custom editor with a Kendo UI Popup?

Solution

The following example demonstrates how to implement this scenario.

    <div id="spreadsheet" style="width: 100%;"></div>
    <script>
      kendo.spreadsheet.registerEditor("popup", function(){
        var context, dlg, model;

        // Further delay the initialization of the UI until the `edit` method is
        // actually called, so here just return the object with the required API.
        return {
          edit: function(options) {
            context = options;
            open();
          },
          icon: "k-font-icon k-i-background"
        };

        // This function actually creates the UI if not already there, and
        // caches the dialog and the model.
        function create() {
          if (!dlg) {
            model = kendo.observable({
              value: "#000000",
              ok: function() {
                // This is the result when OK is clicked. Invoke the
                // callback with the value.

                context.callback(model.value);
                dlg.close();
              },
              cancel: function() {
                dlg.close();
              }
            });
            var el = $("<div data-visible='true' data-role='popup' data-origin='top right' data-position='top left' data-collision='fit' data-width='200'>" +
                       "  <div data-role='flatcolorpicker' data-bind='value: value'></div>" +
                       "  <div style='margin-top: 1em; text-align: right'>" +
                       "    <button style='width: 5em' class='k-button' data-bind='click: ok'>OK</button>" +
                       "    <button style='width: 5em' class='k-button' data-bind='click: cancel'>Cancel</button>" +
                       "  </div>" +
                       "</div>");
            kendo.bind(el, model);

            // Cache the dialog.
            dlg = el.getKendoPopup();
          }
        }

        function open() {
          create();
          dlg.setOptions({
            anchor: $(".k-spreadsheet-editor-button")
          })
          dlg.open();

          var value = context.range.value();
          if (value != null) {
            model.set("value", value);
          }
        }
      });

      $(function() {
        $("#spreadsheet").kendoSpreadsheet({
          sheetsbar: false,
          excel: {
            // Required to enable Excel Export in some browsers
            proxyURL: "//demos.telerik.com/kendo-ui/service/export"
          },
          sheets: [{
            rows: [{
              cells: [
                { value: "Select color:", bold: true },
                { background: "#fef0cd",
                 editor: "popup" }
              ]
            }]
          }]
        });
      });
    </script>
