Vb.net SqlDataSource delete语句不起作用

是否有人可以帮助我编写代码，代码段最后一行出现错误，错误为：其他信息：数据源“”不支持删除，除非指定了DeleteCommand

Dim ds As New SqlDataSource(sConnectionString, "DELETE FROM dbo.NUVIDA_LT_ASSESSMENTS WHERE ASSESSMENTS_ID = @ASSESSMENTS_ID")
ds.DeleteParameters.Add("ASSESSMENT_ID", ASSESSMENT_ID)

Dim x As Integer = ds.Delete()

您正在将delete语句传递给SqlDataSource对象的SELECT语句。所以它抛出了不支持的delete命令

为什么不只使用SqlCommand和ExecuteOnQuery方法呢

Using connection As New SqlConnection(sConnectionString)
    Dim myDelCommand As New SqlCommand("DELETE FROM dbo.NUVIDA_LT_ASSESSMENTS WHERE ASSESSMENTS_ID = @ASSESSMENTS_ID", connection)
    myDelCommand.Parameters.Add("@ASSESSMENTS_ID", SqlDbType.Int)
    myDelCommand.Parameters("@ASSESSMENTS_ID").Value = 123
    myDelCommand.Connection.Open()
    myDelCommand.ExecuteNonQuery()
End Using

好的，很酷，我不知道该怎么做？对vb来说还是很新的programming@AndreaVisnenzaAndy，我加了一个例子。
