Property Value
Type | Default | Description |
---|---|---|
Int32 | 10 | The number of rows displayed on a page. |
Remarks
Use the PageSize
property to specify the maximum number of rows displayed on a page. If you set this property to 0 or a negative value, the TreeList displays one row on each page.
You can display the page size selector, which allows users to change the page size at runtime. Once a user selects a new value in this selector, the PageSize
property value is updated and the TreeList is redrawn.
The PageSize
property is not in effect if any of following properties is set to true
:
The following code snippet changes the maximum number of rows displayed on a page:
@inject EmployeeTaskService EmployeeTaskService
<DxTreeList Data="TreeListData" KeyFieldName="Id" ParentKeyFieldName="ParentId" PageSize="4">
<Columns>
<DxTreeListDataColumn FieldName="Name" Caption="Task" />
<DxTreeListDataColumn FieldName="EmployeeName" />
<DxTreeListDataColumn FieldName="StartDate" />
<DxTreeListDataColumn FieldName="DueDate" />
</Columns>
</DxTreeList>
@code {
List<EmployeeTask> TreeListData { get; set; }
protected override void OnInitialized() {
TreeListData = EmployeeTaskService.GenerateData();
}
}
The TreeList displays the vertical scrollbar when the height of the TreeList content exceeds the height of the component itself. In the image below, the TreeList height is limited to 300px and the PageSize
property is set to 12.
