## Details

This component displays lists of tasks related to the application name insterted. Extra filtering can be provided by applying extra input parameters.

### Setting the column schema

You can use an HTML-based schema declaration to set a column schema for the tasklist as shown below:

```html
<adf-cloud-task-list ...>
    <data-columns>
        <data-column key="name" title="NAME" class="full-width name-column"></data-column>
        <data-column key="created" title="Created" class="hidden"></data-column>
    </data-columns>
</adf-cloud-task-list>
```

You can also set a static custom schema declaration in `app.config.json` as shown below:

```json
"adf-cloud-task-list": {
        "presets": {
            "customSchema": [
            {
                    "key": "name",
                    "type": "text",
                    "title": "name",
                    "sortable": true
            }],
            "default": [
                {
                    "key": "name",
                    "type": "text",
                    "title": "name",
                    "sortable": true
            }],
        }
}
```

```html
<adf-cloud-task-list
    [appId]="'1'"
    [presetColumn]="'customSchema'">
</adf-cloud-task-list>
```

You can use an HTML-based schema and an `app.config.json` custom schema declaration at the same time:

```json
"adf-cloud-task-list": {
        "presets": {
            "customSchema": [
            {
                    "key": "id",
                    "type": "text",
                    "title": "Id",
                    "sortable": true
            }],
            "default": [
                {
                    "key": "name",
                    "type": "text",
                    "title": "name",
                    "sortable": true
            }],
        }
}
```

<!-- {% raw %} -->

```html
<adf-cloud-task-list
    [appName]="'appName'">
    <data-columns>
        <data-column key="assignee" title="Assignee" class="full-width name-column">
            <ng-template let-entry="$implicit">
                    <div>{{getFullName(entry.row.obj.assignee)}}</div>
            </ng-template>
        </data-column>
    </data-columns>
</adf-cloud-task-list>
```

<!-- {% endraw %} -->

### Setting Sorting Order for the list

You can specify a sorting order as shown in the example below:

```ts
let sorting = { orderBy: 'created', direction: 'desc' };
```

```html
<adf-cloud-task-list
    [appId]="'1'"
    [sorting]="[sorting]">
</adf-cloud-task-list>
```

### Pagination strategy

The Tasklist also supports pagination as shown in the example below:

```html
<adf-cloud-task-list #taskCloud
                        [appName]="'APPLICATION-NAME'">
</adf-cloud-task-list>
<adf-pagination [target]="taskCloud"
                (changePageSize)="onChangePageSize($event)">
</adf-pagination>
```

### DataTableAdapter example

See the [`DataTableAdapter`](../../../lib/core/src/lib/datatable/data/datatable-adapter.ts) page for full details of the interface and its standard
implementation, [`ObjectDataTableAdapter`](../../../lib/core/src/lib/datatable/data/object-datatable-adapter.ts). Below is an example of how you can set up the adapter for a
typical tasklist.

```json
[
 {"type": "text", "key": "id", "title": "Id"},
 {"type": "text", "key": "name", "title": "Name", "cssClass": "full-width name-column", "sortable": true},
 {"type": "text", "key": "formKey", "title": "Form Key", "sortable": true},
 {"type": "text", "key": "created", "title": "Created", "sortable": true}
]
```

### DataColumn Features

You can customize the styling of a column and also add features like tooltips and automatic translation of column titles. See the [`DataColumn`](../../../lib/core/src/lib/datatable/data/data-column.model.ts) page for more information about these features.

#### showRowContextMenu event

Emitted before the context menu is displayed for a row.

Note that the [`TaskListCloudComponent`](../../process-services-cloud/components/task-list-cloud.component.md) itself does not populate the context menu with items.
You can provide all necessary content via the handler.

```html
<adf-cloud-task-list
    [contextMenu]="true"
    (showRowContextMenu)="onShowRowContextMenu($event)">
</adf-cloud-task-list>
```

Event properties:

```ts
value: {
    row: DataRow,
    col: DataColumn,
    actions: []
}
```

Handler example:

```ts
onShowRowContextMenu(event: DataCellEvent) {
    event.value.actions = [
        {  title: 'Hello Context Action' },
        { ... }
    ]
}
```

![](../../docassets/images/task-list-cloud-context-menu.png)

This event is cancellable. You can use `event.preventDefault()` to prevent the default behavior.

The [`TaskListCloudComponent`](../../process-services-cloud/components/task-list-cloud.component.md) will automatically render the supplied menu items.

See the [ContextMenu](https://www.npmjs.com/package/ng2-alfresco-core)
documentation for more details on the format and behavior of context actions.

#### showRowActionsMenu event

Emitted before the actions menu is displayed for a row.
Requires the `actions` property to be set to `true`.

Event properties:

```ts
value: {
    row: DataRow,
    action: any
}
```

Note that the [`TaskListCloudComponent`](../../process-services-cloud/components/task-list-cloud.component.md) itself does not populate the action menu with items.
You can provide all necessary content via the handler.

This event is cancellable. You can use `event.preventDefault()` to prevent the default behavior.

#### executeRowAction event

Emitted when the user executes a row action.

This usually accompanies a `showRowActionsMenu` event.
The [`TaskListCloudComponent`](../../process-services-cloud/components/task-list-cloud.component.md) itself does not execute actions but provides support for external
integration. If actions are provided using the `showRowActionsMenu` event
then `executeRowAction` will be automatically executed when the user clicks a
corresponding menu item.

```html
<adf-cloud-task-list
    [actions]="true"
    (showRowActionsMenu)="onShowRowActionsMenu($event)"
    (executeRowAction)="onExecuteRowAction($event)">
</adf-cloud-task-list>
```

```ts
import { DataCellEvent, DataRowActionEvent } from '@alfresco/adf-core';

onShowRowActionsMenu(event: DataCellEvent) {
    let myAction = {
        title: 'Hello Action'
        // your custom metadata needed for onExecuteRowAction
    };
    event.value.actions = [
        myAction
    ];
}

onExecuteRowAction(event: DataRowActionEvent) {
    let args = event.value;
    console.log(args.row);
    console.log(args.action);
    window.alert(`My custom action: ${args.action.title}`);
}
```

![](../../docassets/images/task-list-cloud-action-menu.png)

You can use any payloads for row actions. The only requirement for the objects is that they
must have a `title` property.

When an action is selected in the dropdown menu, the [`TaskListCloudComponent`](../../process-services-cloud/components/task-list-cloud.component.md) invokes the `executeRowAction` event.
Use this to handle the response, inspect the action payload (and all custom properties defined
earlier), and perform the corresponding actions.
