V25.1
  • DxTreeList.ShowAllRows Property

    Specifies whether the TreeList displays all rows on one page. To avoid performance issues when the TreeList is bound to a large data source, use the VirtualScrollingEnabled property instead.

    Namespace: DevExpress.Blazor

    Assembly: DevExpress.Blazor.v25.1.dll

    NuGet Package: DevExpress.Blazor

    Declaration

    [DefaultValue(false)]
    [Parameter]
    public bool ShowAllRows { get; set; }

    Property Value

    Type Default Description
    Boolean false

    true to display all rows on one page; otherwise, false.

    Remarks

    Enable this property to ignore the PageSize value and display all data rows on one page. If the total height of all rows exceeds the TreeList height, the TreeList displays the vertical scrollbar. The pager is visible only if it contains the page size selector with the All item.

    Note

    The TreeList renders all data rows simultaneously when the ShowAllRows property is set to true. This can cause performance issues if the TreeList is bound to a large data source. In this case, use the VirtualScrollingEnabled property instead.

    The following code snippet displays all TreeList rows on one page:

    @inject EmployeeTaskService EmployeeTaskService
    
    <DxTreeList Data="TreeListData" KeyFieldName="Id" ParentKeyFieldName="ParentId" ShowAllRows="true">
        <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();
        }
    }
