ArcEngine 数据编辑(IWorkspaceFactory)

数据编辑做过很多次，没怎么出现问题，今天出现了问题，浪费了大半天，记录一下。

问题：修改Featrue的属性，修改后停止编辑，但是没有提示是否保存修改

原因：在编辑数据的时候没有加StartEditOperation方法。

解决办法：在修改数据的时候加上StartEditOperation和StopEditOperation方法

代码如下：

1、打开工作空间和开始编辑　　

 ''' <summary>
    ''' 开始编辑VB
    ''' </summary>
    ''' <remarks></remarks>
    Public Function StartEdit() As Boolean
    If IsNothing(pWorkspaceEdit) Then
      Dim pWorkspaceFactory As IWorkspaceFactory = New ESRI.ArcGIS.DataSourcesGDB.AccessWorkspaceFactory
      Dim dataset As IDataset = pPointFeatureLayer.FeatureClass
      Dim workspace As IWorkspace = pWorkspaceFactory.OpenFromFile(dataset.Workspace.PathName, 0)
      pWorkspaceEdit = workspace
    End If
    pWorkspaceEdit.StartEditing(True)
  End Function

        //开始编辑C#
       if(pWorkspaceEdit==null)
       {
          IWorkspaceFactory pWorkspaceFactory =new ESRI.ArcGIS.DataSourcesGDB.AccessWorkspaceFactory();
          IDataset dataset =pFeatureLayer.FeatureClass as IDataset;
          IWorkspace workspace = pWorkspaceFactory.OpenFromFile(dataset.Workspace.PathName, 0);
          pWorkspaceEdit = workspace as IWorkspaceEdit;
          pWorkspaceEdit.StartEditing(true);
       }

2、开始操作和停止操作

  Public Function StartOperation() As Boolean
    pWorkspaceEdit.StartEditOperation()
    Return True
  End Function
  Public Function StopOperation() As Boolean
    pWorkspaceEdit.StopEditOperation()
    Return True
  End Function

3、保存编辑

    ''' <summary>
    ''' 保存编辑
    ''' </summary>
    ''' <remarks></remarks>
    Public Function StopEdit() As Boolean
    'pWorkspaceEdit.IsBeingEdited()
        Dim bSave As Boolean

        If Not HasEdits() Then
            bSave = False
        Else
            Dim r As System.Windows.Forms.DialogResult
            r = MessageDialog.Show("是否保存编辑？", "提示", Windows.Forms.MessageBoxButtons.YesNoCancel)
            Select Case r
                Case Windows.Forms.DialogResult.Yes
                    bSave = True
                Case Windows.Forms.DialogResult.No
                    bSave = False
                Case Windows.Forms.DialogResult.Cancel
                    Return True
            End Select
        End If
    pWorkspaceEdit.StopEditing(bSave)
        Return True
    End Function
 
   Private Function HasEdits() As Boolean
        Dim bHasEdits As Boolean
        pWorkspaceEdit.HasEdits(bHasEdits)
        Return bHasEdits
    End Function

4、修改数据的地方

  m_editor.StartOperation()
    Dim pFieldIndex As Integer = pTagFeature.Fields.FindField(e.ChangedItem.PropertyDescriptor.Name)
    pTagFeature.Value(pFieldIndex) = e.ChangedItem.Value
    pTagFeature.Store()
    m_editor.StopOperation()
