Use a Third-Party Angular Editor Template in the Grid for AngularJS

Environment

Product Version 2016.2 504
Product Progress Kendo UI Grid

Description

I am trying to bind ng-model in an nz-toggle (a double- and triple-state toggle for Angular directive for Booleans) in the Grid but it is not working.

How can I bind the value in the editor of a third-party Angular editor template when working with the Kendo UI Grid?

Solution

  1. Bind the third-party Angular editor in the Grid by using the ng-model dataItem.field.
  2. Use an event that the third-party library offers so you can mark the dataItem as dirty. As a result, all items which are marked as dirty will be updated at the next sync of the data source.
// grid columns configuration
columns: [
 { field: "Discontinued", width: "130px", template: "<span class='k-dirty' ng-show={{dataItem.dirty}}></span>{{dataItem.Discontinued}}", editor: $scope.discontinuedEditor },
],

// editor declaration - use the on-toggle event handle to mark the dataItem as dirty so you can show the dirty flag in the template above
 $scope.discontinuedEditor = function(container, options) {
   var editor = $("<nz-toggle ng-model='dataItem.Discontinued' on-toggle='dataItem.dirty=true'></nz-toggle>")
   .appendTo(container);
 };

The following example demonstrates the implementation of the suggested approach.

    <script src="https://rawgit.com/tannerlinsley/nz-toggle/master/dist/nz-toggle.min.js">   </script>
    <div id="example" ng-app="KendoDemos">
