Serializing the Control State

In This Topic

The Serializer can also save/load the control state to a file and stream.

Serializing the Control State to Stream

You can use the SaveControlStateToStream and LoadControlStateToStream methods to load/save the entire chart control state to a stream. This is how it's done:

C#	Copy Code
MemoryStream memoryStream = new MemoryStream(); // save the control state chartControl.Serializer.SaveControlStateToStream(memoryStream, PersistencyFormat.Binary, null); // load the controls state memoryStream.Position = 0; chartControl.Serializer.LoadControlStateFromStream(memoryStream, PersistencyFormat.Binary, null);

Copy Code

MemoryStream memoryStream = new MemoryStream();

// save the control state
chartControl.Serializer.SaveControlStateToStream(memoryStream, PersistencyFormat.Binary, null);

// load the controls state
memoryStream.Position = 0;
chartControl.Serializer.LoadControlStateFromStream(memoryStream, PersistencyFormat.Binary, null);

Visual Basic	Copy Code
Dim memoryStream As New MemoryStream ' save the control state chartControl.Serializer.SaveControlStateToStream(memoryStream, PersistencyFormat.Binary, Nothing) ' load the controls state memoryStream.Position = 0 chartControl.Serializer.LoadControlStateFromStream(memoryStream, PersistencyFormat.Binary, Nothing)

Visual Basic

Copy Code

Dim memoryStream As New MemoryStream

' save the control state
chartControl.Serializer.SaveControlStateToStream(memoryStream, PersistencyFormat.Binary, Nothing)

' load the controls state
memoryStream.Position = 0
chartControl.Serializer.LoadControlStateFromStream(memoryStream, PersistencyFormat.Binary, Nothing)

Note that you have to reset the stream position before loading the state:

C#	Copy Code
// go back to the beginning of the stream memoryStream.Position = 0;

Visual Basic	Copy Code
' go back to the beginning of the stream memoryStream.Position = 0

Serializing the Control State to File

Alternatively you can use the SaveControlStateToFile and LoadControlStateFromFile to load/save the control state from a file:

C#	Copy Code
// save the control state chartControl.Serializer.SaveControlStateToFile("c:\\temp\\chart.bin", PersistencyFormat.Binary, null); // load the controls state chartControl.Serializer.LoadControlStateFromFile("c:\\temp\\chart.bin", PersistencyFormat.Binary, null);

Copy Code

// save the control state
chartControl.Serializer.SaveControlStateToFile("c:\\temp\\chart.bin", PersistencyFormat.Binary, null);

// load the controls state
chartControl.Serializer.LoadControlStateFromFile("c:\\temp\\chart.bin", PersistencyFormat.Binary, null);

Visual Basic	Copy Code
' save the control state chartControl.Serializer.SaveControlStateToFile("c:\\temp\\chart.bin", PersistencyFormat.Binary, Nothing) ' load the controls state chartControl.Serializer.LoadControlStateFromFile("c:\\temp\\chart.bin", PersistencyFormat.Binary, Nothing)

Visual Basic

Copy Code

' save the control state
chartControl.Serializer.SaveControlStateToFile("c:\\temp\\chart.bin", PersistencyFormat.Binary, Nothing)

' load the controls state
chartControl.Serializer.LoadControlStateFromFile("c:\\temp\\chart.bin", PersistencyFormat.Binary, Nothing)
