Public Overloads Sub Load( _
   ByVal stream As Stream _
) 

Visual Basic (Usage)	Copy Code
Dim instance As ChartSerializer Dim stream As Stream   instance.Load(stream)

public void Load( 
   Stream stream
)

Parameters

stream

An object derived from the Stream class (e.g. MemoryStream).

The stream where to load the data from.

The following example first serializes all appearance data to a memory stream (only properties with non-default values), and then loads the serialized data. Axis labels are also serialized.

Visual Basic

Copy Code

' Create MemoryStream object Dim myStream As New MemoryStream() ' Save chart appearance properties that have non-default values., as well as axis labels. Chart1.Serializer.Content = SerializationContent.Appearance ' We can concatenate the Content property string and the SerializableContent string, since the Content ' property is implemented internally as the SerializableContent property. Since we use the ' SerializableContent property we also need to persist the ChartArea and Series object's names, ' otherwise these serialized properties will be applied to new ChartArea and Series objects ' when the data is loaded. Chart1.Serializer.SerializableContent += ",DataPoint.AxisLabel,Series.AxisLabels,Series.Name,ChartArea.Name" Chart1.Serializer.Save(myStream) ... ' Load the serialized data Chart1.Serializer.Content = SerializationContent.Appearance Chart1.Serializer.SerializableContent += ",DataPoint.AxisLabel,Series.AxisLabels,Series.Name,ChartArea.Name" Chart1.Serializer.Load (myStream)

C#

Copy Code

// Create MemoryStream object MemoryStream myStream = new System.IO.MemoryStream(); // Save chart appearance properties that have non-default values, as well as axis labels. Chart1.Serializer.Content= SerializationContent.Appearance; // We can concatenate the Content property string and the SerializableContent string, since the Content //   property is implemented internally as the SerializableContent property. Since we use the //   SerializableContent property we also need to persist the ChartArea and Series object's names, //   otherwise these serialized properties will be applied to new ChartArea and Series objects //    when the data is loaded. Chart1.Serializer.SerializableContent += ",DataPoint.AxisLabel,Series.AxisLabels,Series.Name,ChartArea.Name"; Chart1.Serializer.Save (myStream); ... // Load the serialized data. Chart1.Serializer.Content = SerializationContent.Appearance; Chart1.Serializer.SerializableContent += ",DataPoint.AxisLabel,Series.AxisLabels,Series.Name,ChartArea.Name"; Chart1.Serializer.Load(myStream);

Call this method to load serialized data into the Chart control.

When a load operation occurs by default serializable properties are first reset to their default values before they are set to the persisted values (if saved). To change this behavior use the ResetWhenLoaded property.

By default all serialized chart properties will be loaded. To load specific serialized properties set the Content , SerializableContent or NonSerializableContent properties before loading the data.

Note that when data is saved using the Save method only those properties that have non-default values are actually serialized.
