DxRibbonComboBoxItem<TData, TValue>.TextFieldName Property

Specifies the data source field that contains text for combo box items.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v25.1.dll

NuGet Package: DevExpress.Blazor

Declaration

[Parameter]
public string TextFieldName { get; set; }

Property Value

Type	Description
String	The data source field’s name.

Remarks

Use the TextFieldName property when you bind the ribbon combo box item to a data source that stores custom objects (IEnumerable<CustomType>). This property specifies the name of the data source field that stores text for the combo box items.

If the TextFieldName property is not specified, the item searches for the Text field in the data source and uses this field as the text field. Otherwise, the editor populates its items with CustomType.ToString() values.
