Property Value

Type	Default	Description
Boolean	true	true, if the drop-down window is displayed; otherwise, false.

Remarks

Use the DropDownVisible property to show/hide the editor’s drop-down window. To respond to changes to the property, handle the DropDownVisibleChanged event.

<DxComboBox Data="@Cities"
            DropDownVisible="@DropDownVisible"
            DropDownVisibleChanged="@((value) => OnDropDownVisibleChanges(value))">
</DxComboBox>

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

  bool DropDownVisible = true;

  void OnDropDownVisibleChanges(bool value) {
    DropDownVisible = value; 
    // ...
  }
}

To display the editor’s drop-down window from code, you can also call the ShowDropDown() method.
