Name	Type	Description
args	DevExpress.XtraBars.Docking2010.Views.WindowsUI.INavigationArgs	An INavigationArgs object that stores data related to the current navigation process.

Remarks

You can pass specific information when navigating through a Content Containers. To do so, implement the ISupportNavigation interface for your Documents’ content. After you have implemented the interface methods, use the OnNavigatedFrom method to assign required data to the Parameter property. This data will be passed to the ISupportNavigation.OnNavigatedTo method for the control to which an end-user navigates. For example, the following code passes the selected GridControl row from userControl1 to userControl2 when navigating.

C#

//userControl1
public partial class userControl1 : UserControl, ISupportNavigation {
    . . .
    public void OnNavigatedFrom(INavigationArgs args) {
        args.Parameter = gridView1.GetDataRow(gridView1.FocusedRowHandle);
    }
}

//userControl2
public partial class userControl2 : UserControl, ISupportNavigation {
    . . .
    public void OnNavigatedTo(INavigationArgs args) {
        //do something with args.Parameter
    }
}

VB.NET

'userControl1
Public Partial Class userControl1
    Inherits UserControl
    Implements ISupportNavigation
    . . .
    Public Sub OnNavigatedFrom(ByVal args As INavigationArgs)
        args.Parameter = gridView1.GetDataRow(gridView1.FocusedRowHandle)
    End Sub
End Class

'userControl2
Public Partial Class userControl2
    Inherits UserControl
    Implements ISupportNavigation
    . . . 
    Public Sub OnNavigatedTo(ByVal args As INavigationArgs)
        'do something with args.Parameter
    End Sub
End Class
