DataRowView.BeginEdit Method

Begins an edit procedure.

Namespace:  System.Data
Assembly:  System.Data (in System.Data.dll)
'Declaration
Public Sub BeginEdit

Implements

IEditableObject.BeginEdit

Use AddNew to add a DataRowView.

The BeginEdit method is identical to the DataRow.BeginEdit method of the DataRow. After calling BeginEdit, any changes made to the DataRowView can be rolled back by calling CancelEdit. Call the BeginEdit method before allowing users to change row values. After values have been changed, you retrieve the new values by setting the RowVersion to DataRowVersion.Proposed. Check the values with a business rule, and roll back the changes if needed by calling CancelEdit, or call EndEdit to accept the changes.

The following example edits a row in a DataRowView. calling the BeginEdit before, and EndEdit afterwards.

Private Sub EditDataRowView(rowView As DataRowView, _
    columnToEdit As String)
    rowView.BeginEdit()
    rowView(columnToEdit) = textBox1.Text

    ' Validate the input with a function. 
    If ValidateCompanyName(rowView(columnToEdit)) Then
        rowView.EndEdit()
    Else
        rowView.CancelEdit()
    End If 
End Sub 

Private Function ValidateCompanyName( _
    valuetoCheck As Object) As Boolean 
    ' Insert code to validate the value. 
    Return True 
End Function
