Specifies the current state (displayed/hidden) of a drop-down window.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.2.dll

NuGet Package: DevExpress.Blazor

C#

[Parameter]
public bool DropDownVisible { get; set; }

#Property Value

Type Default Description
Boolean false

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 the property change, handle the DropDownVisibleChanged event.

Razor
<DxDropDownBox @bind-Value="Value" QueryDisplayText="QueryText"
            DropDownVisible="@DropDownVisible"
            DropDownVisibleChanged="@((value) => OnDropDownVisibleChanges(value))">
    @* ... *@
</DxDropDownBox>

@code {
  object Value { get; set; }
  bool DropDownVisible = true;

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

You can also call ShowDropDown() and HideDropDown() methods to show and hide drop-down window.
