Description

How to add a button to every cell in a column that invokes the Kendo UI Editor band to that cell?

Possible Solution

1. Use a columns.template to add a button to the cell.
2. Once the user clicks the button, invoke a window that contains an editor to modify the data item of the cell.

<div id="grid"></div>
<div id="window">
    <textarea id="editor" rows="10" cols="30" style="height:440px" aria-label="editor" data-bind="value: text"></textarea>
</div>
<script>
    var dataItem;

    $("#grid").kendoGrid({
        columns: [{
                field: "name"
            },
            {
                field: "text",
                template: "<div class='contentDivs' style='white-space: nowrap; height: 25px; overflow: hidden; max-width:65%; float: left;'>#= text #</div><button class='editButtons' style='float:right'>Edit</button>",
                width: "300px"
            },
            {
                field: "age"
            }
        ],
        dataSource: {
            data: [{
                    name: "Jane Doe",
                    text: "Lorem ipsum dolor lis in magna. In feugiat non ipsum a laoreet. Nulla facilisi.",
                    age: 30
                },
                {
                    name: "John Doe",
                    text: "Cras vitae nisl quis nulla accumsan porttitor a eget quam. Vestibulum tempor eu felis ac pulvinar. Morbi viverra odio sit ame. Pellentesque felis est, condimentum et pellentesque vel, luctus eget libero. Morbi non placerat diam, quis tincidunt ante.",
                    age: 33
                }
            ]
        },
        dataBound: onDataBound
    });

    function onDataBound(e) {
        $(".contentDivs").children().css("display", "table-cell");
        $(".editButtons").kendoButton({
            click: function(e) {
                var grid = $("#grid").data("kendoGrid");
                var editor = $("#editor").data("kendoEditor");
                var window = $("#window").data("kendoWindow");
                var row = e.sender.element.closest("tr");
                var dataItem = grid.dataItem(row);

                kendo.bind(editor.element, dataItem);
                window.open().center();
            }
        });
    };

    $("#window").kendoWindow({
        width: "600px",
        visible: false,
        modal: true,
        close: function(e) {
            e.sender.element.focus()
        },
        actions: [
            "Maximize",
            "Close"
        ],
    });
    $("#editor").kendoEditor();
</script>
