Namespace: DevExpress.Blazor
Assembly: DevExpress.Blazor.v20.2.dll
NuGet Package: DevExpress.Blazor
Declaration
[DefaultValue(false)]

public bool DropDownVisible { get; set; }
Property Value
Type | Default | Description |
---|---|---|
Boolean | **false** | true, if the drop-down window is displayed; otherwise, false. |
Remarks
Each Toolbar item can have multiple child items which are specified as elements of the parent item’s Items collection. A root-level toolbar item that has child items is rendered as a drop-down button that displays a hierarchical pop-up menu when clicked.
Use the DropDownVisible property to show/hide a drop-down item’s children. To respond to the property change, handle the DropDownVisibleChanged event.

}
You can handle an drop-down item’s button as one button or split it into two buttons - a regular button and a drop-down button that invokes a pop-up window. To enable this behavior, set the SplitDropDownButton property to true.
