I have a kendo grid with a column that has a row template that is a checkbox. When it is selected, it marks that row as selected so that I can operate on a subset of the rows selected by the user.

I wish to place a checkbox in the column header that will check or uncheck every row in the grid.

I have tried adding a headerTemplate with a checkbox but I do not know how to cause it to select all rows.

Also, for some reason the checkbox in the header does not get checked when I click it, instead when I click it, it appears to try to sort the grid (the asc/desc arrows appear on the header cell). I've tried adding `filterable: false` but this still happens.

My grid is below. The column in question is `select_all`

    <div id="PatrolRecords"
            data-filterable='{ "mode": "row" }'
            data-role='grid'
            data-sortable='true'
            data-detail-template='patrolDetailTemplate'
            data-detail-init='detailInit'
            data-bind='source: reportData, events: {excelExport: excelExportHandler}'
            data-bound='onDataBound'
            data-pageable='{ "pageSize": 10 }'
            data-toolbar='[{ template: kendo.template($("#toolbarTemplate").html()) }]'
            data-excel='{ "fileName": "Patrols.xlsx", "allPages": "true" }'
            data-columns='[
                {
                    field: "address",
                    title: "Address",
                    template: kendo.template($("#addressTemplate").html()),
                    filterable: { cell: { operator: "contains" } }
                },
                {
                    field: "end_date_seconds",
                    title: "Date & Time",
                    template: kendo.template($("#dateTemplate").html()),
                    filterable: false
                },
                {
                    field: "patrolled_by",
                    title: "Patrolled By",
                    filterable: { cell: { operator: "contains" } }
                },
                {
                    field: "select_all",
                    width: 35,
                    headerTemplate: "<input type=\"checkbox\" id=\"chkAll\" />",
                    template: "<input type=\"checkbox\" class=\"check_row\" />",
                    filterable: false
                }
            ]'>
        </div>
