DxDropDown.IsInitialized Property

Gets whether the DropDown component is initialized.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v23.2.dll

NuGet Package: DevExpress.Blazor

Declaration

public bool IsInitialized { get; }

Property Value

Type	Description
Boolean	true if the component is initialized; otherwise, false.

Remarks

The drop-down window cannot be shown until the component is initialized. The initialization starts after the component is rendered for the first time. Once this task is completed, the Initialized event fires.

To track the initialization state from code, use the IsInitialized property. You can run the InitializedTask task to wait until the drop-down window is initialized.
