Information

This demo shows how you can use the TaskBoard's API to validate different actions in the widget:

Tasks with status "Done" are readonly and cannot be moved to other columns.
Only tasks "In Progress" can be moved to "Done".
The maximum number of tasks "In Progress" is 4.

$("#taskBoard").kendoTaskBoard({ columnSettings: { buttons: ["editColumn", "addCard"], }, columns: [ { text: "To-Do", status: "todo" }, { text: "In Progress", status: "inProgress" }, { text: "Done", status: "done" } ], dataSource: { data: cardsData, schema: { model: { id: "id", fields: { id: { type: "number" }, order: { type: "number" }, title: { field: "title", defaultValue: "No title" }, description: { field: "description", validation: { required: true } }, } } }, }, dataOrderField: "order", height: 750, resources: [ { field: "color", dataSource: [ { value: "orange", color: "#ff0000" }, { value: "green", color: "#00ff00" }, { value: "blue", color: "#0000ff" } ] } ], columnsDataBound: onColumnsDataBound, dataBound: onDataBound, moveStart: onMoveStart, moveEnd: onMoveEnd, }); var sourceColumnStatus = ""; function onColumnsDataBound(e) { setReadonlyColumn("done"); } function onDataBound(e) { setReadonlyColumn("done"); } function onMoveStart(e) { sourceColumnStatus = e.column.status; } function onMoveEnd(e) { var taskBoard = e.sender; if (e.action == "receive") { if (e.column.status == "inProgress") { var totalInProgress = taskBoard.itemsByStatus("inProgress").length; if (totalInProgress > 4 & sourceColumnStatus != "inProgress") { e.preventDefault(); alert('No more than 4 tasks can be "In Progress" at the same time.'); } } else if (e.column.status == "done") { if (sourceColumnStatus == "todo") { e.preventDefault(); alert('Only tasks "In Progress" can be moved to "Done".') } } sourceColumnStatus = ""; } } function setReadonlyColumn(status) { var taskBoard = $("#taskBoard").data("kendoTaskBoard"); var cardsDone = taskBoard.itemsByStatus(status); $(cardsDone).each(function (index) { taskBoard.readOnly($(this), true); }); } .demo-section.wide { max-width: 1025px; } .k-taskboard-drag-hint { font: 400 14px Arial,Helvetica,sans-serif; }
