NavBarControl.SaveToStream(Stream) Method

Saves the control’s layout to a stream.

Namespace: DevExpress.XtraNavBar

Assembly: DevExpress.XtraNavBar.v18.2.dll

Declaration

C#

public virtual void SaveToStream(
    Stream stream
)

VB.NET

Public Overridable Sub SaveToStream(
    stream As Stream
)

Parameters

Name	Type	Description
stream	Stream	A System.IO.Stream object to which the control’s layout is written.

Remarks

Use the SaveToStream method to write the NavBarControl control’s layout to a stream. You can read stored settings from the stream via the NavBarControl.RestoreFromStream method.

Note

To allow a layout to be correctly saved and restored, ensure that all nav bar groups and items created at runtime have their names (the Name property) specified.

Example

The following sample code demonstrates the way in which to save the control layout to a stream and then restore it. The NavBarControl.SaveToStream and NavBarControl.RestoreFromStream methods are used for this purpose.

The image below displays two NavBarControl controls before and after code execution. Note that the second control is initially empty (it doesn’t contain any groups and items). Layout information for the first control is saved to a stream. The second control restores it. Note that only the layout of groups and links is saved.

C#

Imports System.IO

FileStream outFile = new FileStream("C:\\NavBarLayout", FileMode.Create);
navBarControl1.SaveToStream(outFile);
outFile.Close();
FileStream inFile = new FileStream("C:\\NavBarLayout", FileMode.Open);
navBarControl2.RestoreFromStream(inFile);
inFile.Close();

VB.NET

Dim OutFile As New System.IO.FileStream("C:\NavBarLayout", IO.FileMode.Create)
NavBarControl1.SaveToStream(OutFile)
OutFile.Close()
Dim InFile As New System.IO.FileStream("C:\NavBarLayout", IO.FileMode.Open)
NavBarControl2.RestoreFromStream(InFile)
InFile.Close()
