Question

我正在寻找一些添加行按钮的帮助，我在插入数据时遇到问题。

这是我收到的错误： Error1：方法'受保护的Sub SqlDataSource2_Inserting（sender As Object，e As System.Web.UI.WebControls.ObjectDataSourceMethodEventArgs）'无法处理事件'Public Event Inserting（sender As Object，e As System.Web.UI.WebControls.SqlDataSourceCommandEventArgs）'因为他们没有兼容的签名。 C：\ Users \ Administrator \ Documents \ Visual Studio 2012 \ Projects \ Certificates \ Certificates \ WebForm1.aspx.vb 17 161证书

这是我的vb代码：

公共类WebForm1 继承System.Web.UI.Page

受保护的子Page_Load（ByVal sender As Object，ByVal e As System.EventArgs）处理Me.Load

End Sub

Private Sub GridView1_RowCommand（sender as Object，e As GridViewCommandEventArgs）处理Laboratory.RowCommand '如果CommandName ==“插入”，则插入数据 '和验证控件表示有效数据...... 如果e.CommandName =“Insert”AndAlso Page.IsValid Then '插入新纪录...... SqlDataSource2.Insert（）万一结束子
