DxTreeListDataColumn.FieldName Property

Specifies a data field that supplies column values.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.2.dll

NuGet Package: DevExpress.Blazor

#Declaration

C#
[DefaultValue(null)]
[Parameter]
public string FieldName { get; set; }

#Property Value

Type Default Description
String null

The field name.

#Remarks

Use the Data property to bind the TreeList to a data collection. To display data within the TreeList, declare DxTreeListDataColumn objects in the Columns template and use the FieldName property to assign data fields. These data fields should be implemented as properties.

To bind a column to a complex field (a field that belongs to a data collection’s nested object), use the following syntax: NestedObject.FieldName.

The TreeList creates user-friendly column captions based on field names. The component adds spaces between words when a field is named according to the CamelCase naming convention. You can use the Caption property to specify a custom caption.

@inject EmployeeTaskService EmployeeTaskService

<DxTreeList Data="TreeListData" KeyFieldName="Id" ParentKeyFieldName="ParentId">
    <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();
    }
}
