#Declaration

public class DxComboBoxDropDownButton :
    DxEditorDropDownButtonBase

#Remarks

The DxComboBox<TData, TValue> component shows the built-in drop-down button that invokes a menu. You can set the ShowDropDownButton property to false to hide this button.

You can also add a custom drop-down button to the ComboBox:

Add the <Buttons></Buttons> tag to the component’s markup to define the Buttons collection.
Add a DxComboBoxDropDownButton object.
Set up button properties to customize the button:
- CssClass
- Position
- Enabled
- and so on

The following code snippet hides the built-in drop-down button, adds a new drop-down button, and specifies its position.

Razor

<DxComboBox Data="@Cities" @bind-Value="@Value" ShowDropDownButton=false>
    <Buttons>
        <DxComboBoxDropDownButton Position="EditorButtonPosition.Left"/>
    </Buttons>
</DxComboBox>

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

  string Value { get; set; }
}
