卡片状态

一张卡片可以处于以下三种状态当中的一个：

• 启用（默认）
• 禁用
• 只读

您可以禁用/启用单个卡，或列中的所有卡。

以下示例演示了如何禁用特定卡。

<div id="taskBoard"></div>

<script>
var taskBoard = $("#taskBoard").kendoTaskBoard({
dataOrderField: "order",
dataSource: [
{ id: 1, order: 1, title: "Task 1", description: "Description 1", status: "backlog", category: "red" },
{ id: 2, order: 2, title: "Task 11", description: "Description 11", status: "backlog", category: "red" },
{ id: 3, order: 3, title: "Task 2", description: "Description 2", status: "doing", category: "green" },
{ id: 4, order: 4, title: "Task 22", description: "Description 22", status: "doing", category: "green" },
{ id: 5, order: 5, title: "Task 3", description: "Description 3", status: "done", category: "blue" }
],
columns: [
{ text: "Doing", status: "doing" },
{ text: "Backlog", status: "backlog" },
{ text: "Done", status: "done" }
]
}).data("kendoTaskBoard");

taskBoard.enable(taskBoard.items().eq(0), false);
</script>

您还可以将只读状态设置为特定卡或列中的所有卡。

以下示例演示如何将列中的所有卡片设置为只读。

<div id="taskBoard"></div>

<script>
var taskBoard = $("#taskBoard").kendoTaskBoard({
dataOrderField: "order",
dataSource: [
{ id: 1, order: 1, title: "Task 1", description: "Description 1", status: "backlog", category: "red" },
{ id: 2, order: 2, title: "Task 11", description: "Description 11", status: "backlog", category: "red" },
{ id: 3, order: 3, title: "Task 2", description: "Description 2", status: "doing", category: "green" },
{ id: 4, order: 4, title: "Task 22", description: "Description 22", status: "doing", category: "green" },
{ id: 5, order: 5, title: "Task 3", description: "Description 3", status: "done", category: "blue" }
],
columns: [
{ text: "Doing", status: "doing" },
{ text: "Backlog", status: "backlog" },
{ text: "Done", status: "done" }
]
}).data("kendoTaskBoard");

taskBoard.readOnlyByColumn(taskBoard.columns().eq(0));
</script>

卡片菜单

TaskBoard在每张卡片中呈现一个菜单按钮，提供删除或编辑卡片的选项，单击它们将分别执行 DeleteCardCommand 或 EditCardCommand。

可用的卡片命令有：

• SelectCardCommand
• SaveChangesCommand
• DeleteCardCommand
• MoveCardCommand
• EditCardCommand
• AddCardCommand

可以通过 cardMenu 配置添加其他自定义按钮。

下面的示例演示如何使用自定义按钮来执行卡片菜单中的自定义命令。

<div id="taskBoard"></div>

<script>
$("#taskBoard").kendoTaskBoard({
dataOrderField: "order",
dataSource: [
{ id: 1, order: 1, title: "Task 1", description: "Description 1", status: "backlog", category: "red" },
{ id: 2, order: 2, title: "Task 11", description: "Description 11", status: "backlog", category: "red" },
{ id: 3, order: 3, title: "Task 2", description: "Description 2", status: "doing", category: "green" },
{ id: 4, order: 4, title: "Task 22", description: "Description 22", status: "doing", category: "green" },
{ id: 5, order: 5, title: "Task 3", description: "Description 3", status: "done", category: "blue" }
],
columns: [
{ text: "Backlog", status: "backlog" },
{ text: "Doing", status: "doing" },
{ text: "Done", status: "done" }
],
cardMenu: [ { name: "CustomButton", text: "My Custom Tool", icon: "gear", command: "MyCustomCommand", options: "myvalue" } ]
});

kendo.ui.taskboard.commands["MyCustomCommand"] = kendo.ui.taskboard.Command.extend({
exec: function () {
var taskboard = this.taskboard;
var options = this.options;
var card = options.card;
var cardElm = options.cardElement;
var column = options.column;
var columnElm = options.columnElement;

cardElm.css("border", "solid red 3px");
columnElm.css("border", "solid red 3px");
alert(kendo.format("{0} Card executed Custom command in column with status {1} with value {2}", card.get("title"), column.get("status"), options.value));
}
});
</script>
