Question

我有一个简单的输入表单，想在用户插入数据后包含一条感谢信息。我的OnInserting="SqlDataSource1_Inserted"方法无效。我是编程的新手所以没有判断力：/

error message:
CS0123: No overload for 'SqlDataSource1_Inserted' matches delegate 'System.Web.UI.WebControls.SqlDataSourceCommandEventHandler'

Line 36:     </p>
Line 37:     <p>
Line 38:         <asp:SqlDataSource ID="SqlDataSource1" runat="server" 
Line 39:             ConnectionString="<%$ ConnectionStrings:TESTConnectionString %>"

标记：

<body>
    <form id="form1" runat="server">        
    <p>
        <asp:DetailsView ID="DetailsView1" runat="server" AutoGenerateRows="False"

            OnInserting="SqlDataSource1_Inserted"    
            ProviderName="<%$ ConnectionStrings:TESTConnectionString.ProviderName %>" 
            SelectCommand="SELECT text_test FROM test" >
            <DeleteParameters>
                <asp:Parameter Name="id" Type="Int32" />
            </DeleteParameters>
            <InsertParameters>
                <asp:Parameter Name="text_test" />
            </InsertParameters>
        </asp:SqlDataSource>
    </p>
    </form>
</body>
</html>

代码隐藏：

protected void SqlDataSource1_Inserted(object sender, ObjectDataSourceStatusEventArgs e)
{
    if (e.AffectedRows > 0)
    {
        Response.Write("<script language='javascript'> { alert('a message');}</script>");   
    }
}

Answer 1

它可能是您需要的OnInserted事件，而不是OnInserting（在您的aspx中）。

这是在插入后引发的。

删除回复消息上的大括号

 Response.Write("<script language='javascript'>  alert('a message');</script>");

Answer 3

@MG，

您需要处理已插入事件，但请查看您的代码，插入

...
oninserted="SqlDataSource1_Inserted"
..

插入后的消息
