Setting the column schema

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

<adf-tasklist ...>
    <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-tasklist>

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

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

<adf-tasklist 
    [appId]="'1'" 
    [presetColumn]="'customSchema'">
</adf-tasklist>

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

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

<adf-tasklist
    [appId]="'1'" 
    [presetColumn]="'customSchema'">
    <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-tasklist>

Setting Sorting Order for the list

you can pass sorting order as shown in the example below:

// Possible values are : `created-desc`, `created-asc`, `due-desc`, `due-asc`
let sortParam = 'created-desc'; 

<adf-tasklist
    [appId]="'1'"
    [sort]="sortParam">
</adf-tasklist>

Pagination strategy

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

<adf-tasklist
    [appId]="'1'"
    [page]="page"
    [size]="size"
    #taskList>
</adf-tasklist>
<adf-pagination
    *ngIf="taskList"
    [target]="taskList"
    [supportedPageSizes]="supportedPages"
    #taskListPagination>
</adf-pagination>

DataTableAdapter example

See the DataTableAdapter page for full details of the interface and its standard implementation, ObjectDataTableAdapter. Below is an example of how you can set up the adapter for a typical tasklist.

[
 {"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 page for more information about these features.

Show custom template when tasklist is empty

You can add your own template or message as shown in the example below:

<adf-tasklist>
    <adf-empty-custom-content>
        Your Content
    </adf-empty-custom-content>
<adf-tasklist>
