View.Close(Boolean) Method

Closes a View if it is allowed to be closed.

Namespace: DevExpress.ExpressApp

Assembly: DevExpress.ExpressApp.v25.2.dll

NuGet Package: DevExpress.ExpressApp

Declaration

C#

public bool Close(
    bool checkCanClose
)

VB.NET

Public Function Close(
    checkCanClose As Boolean
) As Boolean

Parameters

Name	Type	Description
checkCanClose	Boolean	true if the View.QueryCanClose event should be raised; otherwise, false.

Returns

Type	Description
Boolean	true if a View was closed successfully; otherwise, false.

Remarks

Use this method to close a View. Pass true if you need to raise the View.QueryCanClose event. The Close method does not close the View if the View.QueryCanClose event handler sets the CancelEventArgs.Cancel parameter to true.

Note

XAF does not trigger the QueryCanClose event in ASP.NET Core Blazor applications. Use the DevExpress.ExpressApp.Blazor.BlazorWindow.Closing event to prohibit closing a View under certain conditions.

If a View can be closed, the Close method raises the View.Closing and View.Closed events.

This method is used internally with the parameter set to true.
