Public Overloads Sub Save( _
   ByVal writer As TextWriter _
) 

Visual Basic (Usage)	Copy Code
Dim instance As ChartSerializer Dim writer As TextWriter   instance.Save(writer)

public void Save( 
   TextWriter writer
)

Parameters

writer

An object derived from TextWriter (e.g. StringWriter class) used to save chart properties.

Text writer to save the data.

The following example persists the appearance view state at the client. Note that the ViewStateData property represents the actual data persisted in the web document.

Visual Basic	Copy Code
Imports System.IOImports Dundas.Charting.Webcontrol ... ' Serialize the view state data Dim sw As New StringWriter() Chart1.Serializer.Content = SerializationContent.Appearance Chart1.Serializer.Save(sw) ' Set the view state data Chart1.ViewStateData = sw.ToString()

C#	Copy Code
using System.IO; using Dundas.Charting.Webcontrol; ... // Serialize the view state data StringWriter sw = new StringWriter(); Chart1.Serializer.Content = SerializationContent.Appearance; Chart1.Serializer.Save(sw); // Set the view state data Chart1.ViewStateData = sw.ToString();

By default all chart properties with non-default values (this includes data points) will be serialized when this method is called. To control what chart characteristics are serialized use the Content, SerializableContent and NonSerializableContent properties.

When using this definition the format (set by the Format property) must be XML.

If the ViewStateData property is used to persist state then this method can be used to save the serialized data to an object derived from TextWriter, which is then used to write the data to the ViewStateData property. For more information see the State Management topic (also see the sample code below).
