    Remarks

    Note

    When the TreeList is bound to the GridDevExtremeDataSource or loads data on demand, call the WaitForRemoteSourceRowLoadAsync(Int32) method before you execute the GetRowValue method to ensure that the specified data row is loaded.

    The following example displays information about the first visible row:

    @inject EmployeeTaskService EmployeeTaskService
    
    <style>
        .my-button {
            width: 200px;
        }
    </style>
    
    <DxTreeList @ref="@MyTreeList" Data="TreeListData" KeyFieldName="Id" ParentKeyFieldName="ParentId">
        <Columns>
            <DxTreeListDataColumn FieldName="Name" Caption="Task" />
            <DxTreeListDataColumn FieldName="EmployeeName" />
            <DxTreeListDataColumn FieldName="StartDate" />
            <DxTreeListDataColumn FieldName="DueDate" />
        </Columns>
    </DxTreeList>
    <DxButton Click="@OnClick" CssClass="my-button" Text="Get the First Task" />
    <p></p>
    Task Name: @RowValue
    
    @code {
        ITreeList MyTreeList { get; set; }
        object RowValue { get; set; }
        List<EmployeeTask> TreeListData { get; set; }
    
        protected override void OnInitialized() {
            TreeListData = EmployeeTaskService.GenerateData();
        }
        void OnClick() {
            RowValue = MyTreeList.GetRowValue(0, "Name");
        }
    }
