Remarks

The Clear button allows users to clear (set to null) an editor value. The button can be displayed when the editor is not in the read-only state. Use an editor’s ClearButtonDisplayMode property to specify the clear button’s visibility.

The following code snippet displays the clear button in the DxComboBox<TData, TValue>.

<DxComboBox Data="@Cities" 
            ClearButtonDisplayMode="DataEditorClearButtonDisplayMode.Auto"
            NullText="Select City..."
            @bind-Value="@Value"/>

@code {
    string Value { get; set; }
    IEnumerable<string> Cities = new List<string>() { "London", "Berlin", "Paris", };
}
