慎用DataGrid的CurrentRowIndex操作DataTable

    '在DataGrid的AllowSorting值为True的情形下,利用CurrentRowIndex来取DataTable中相应的Row是不大妥当的。

    '在随意中进行了某列排序后,CurrentRowIndex与DataTable的“CurrentRowIndex”就有可能不相符,

    'DataTable1.Rows[DataGrid1.CurrentRowIndex]可能并不是你真正要的。

    '稳妥的方法可以这样：

 

 

    Dim MyCurrencyManager As CurrencyManager

 

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        '......

        MyCurrencyManager = Me.BindingContext(DataGrid1.DataSource, DataGrid1.DataMember)

    End Sub

 

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

        CType(MyCurrencyManager.Current, DataRowView).Row.Delete()

    End Sub
