Examples

The following code demonstrates using the ToggleScope method. This code is part of a larger code sample found in the WebPartPersonalization class description.

// Allows authorized user to change personalization scope.
protected void Toggle_Scope_Button_Click(object sender, EventArgs e)
{
    if (_manager.Personalization.CanEnterSharedScope)
    {
        _manager.Personalization.ToggleScope();
    }
    
}

' Allows authorized user to change personalization scope.
Protected Sub Toggle_Scope_Button_Click(ByVal sender As Object, ByVal e As EventArgs) 
    If _manager.Personalization.CanEnterSharedScope Then
        _manager.Personalization.ToggleScope()
    End If

End Sub 'Toggle_Scope_Button_Click

Remarks

This method toggles the currently executing page's personalization scope. Toggling the scope results in a Transfer back to the current executing page.

This method performs no operation if it is called while an export or import of a Web Parts control is occurring.

If a toggle scope request occurs for a page that was submitted via a POST request, then any query string values will be preserved during the transfer; query string parameters are not preserved if the page was submitted via a GET request.
