DxDrawer.IsOpen Property

Specifies whether the drawer panel is open.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.2.dll

NuGet Package: DevExpress.Blazor

#Declaration

C#
[Parameter]
public bool IsOpen { get; set; }

#Property Value

Type Description
Boolean

true if the drawer is open; otherwise, false.

Implement two-way binding for the IsOpen property to open and close the drawer panel in code and update the property value when the drawer panel closes in response to a user click on a content area. The IsOpenChanged event occurs when the property value changes.
