シンタックス

Visual Basic

'宣言
 
Public Overloads Sub SaveAsBinary( _
   ByVal filename As String, _
   ByVal includeData As Boolean _
) 

C#

public void SaveAsBinary( 
   string filename,
   bool includeData
)

パラメータ

filename

シリアル化された UltraDataSource 情報を含むファイルの名前。

includeData

データ構造と共にデータが保存されているかどうかを指定します。

解説

SaveAsBinary メソッドは、UltraDataSource のプロパティ設定およびレイアウトを永続化するために LoadFromBinary(String,Boolean) メソッドと組み合わせて使用します。

使用例

Visual Basic

Imports Infragistics.Shared
Imports Infragistics.Win
Imports Infragistics.Win.UltraWinDataSource


    Private Sub SaveButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles saveButton.Click
        ' Following code saves the data to an XML file for loading at
        ' a later time.

        Dim saveFileDlg As SaveFileDialog = New SaveFileDialog()
        saveFileDlg.Filter = "XML File|*.xml"
        saveFileDlg.OverwritePrompt = True
        Dim dialogResult As DialogResult = saveFileDlg.ShowDialog(Me)

        If dialogResult.OK = dialogResult Then
            ' Pass in true for the includeData parameter to save the data
            ' otherwise it will only save the structure.
            '
            Me.ultraDataSource1.SaveAsXml(saveFileDlg.FileName, True)
        End If
    End Sub

    Private Sub LoadButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles loadButton.Click
        ' Following code loads previously saved data from a file.

        Dim openFileDlg As OpenFileDialog = New OpenFileDialog()
        openFileDlg.Filter = "XML File|*.xml"
        Dim dialogResult As DialogResult = openFileDlg.ShowDialog(Me)

        If dialogResult.OK = dialogResult Then
            ' Pass in true for the includeData parameter to load the data
            ' and not just the structure.
            '
            Me.ultraDataSource1.LoadFromXml(openFileDlg.FileName, True)
        End If
    End Sub
