Question

我有这个转发器

<asp:Repeater ID="Repeater1" runat="server">
    <ItemTemplate>
                <div class="detail">
                    <asp:Label ID="LabelID" runat="server" Visible="true" Text='<%#DataBinder.Eval(Container.DataItem, "Id") %>'>'></asp:Label><br />
                    <b>Namn:</b>&nbsp;<asp:Label ID="Label1" runat="server" Text='<%#Eval("Namn") %>'>'></asp:Label>&nbsp;<br />
                    <b>Address</b>&nbsp;<asp:Label ID="Label3" runat="server" Text='<%#Eval("Adress") %>'></asp:Label><br />
                    <b>Telefonnummer</b>&nbsp;<asp:Label ID="Label4" runat="server" Text='<%#Eval("Telefonnummer") %>'></asp:Label><br />
                    <b>Mailaddres</b>&nbsp;<asp:Label ID="Label5" runat="server" Text='<%#Eval("Epost-address") %>'></asp:Label><br />
                    <b>Meddelande:</b>&nbsp;<asp:Label ID="Label6" runat="server" Text='<%#Eval("Kommentar") %>'></asp:Label><br />
                    <asp:LinkButton ID="lnkDelete" runat="server" CommandArgument='<%#Eval("Id") %>' CommandName="Delete" onclientclick="return confirm('Are you sure you want to delete?')">Delete</asp:LinkButton>
                </div>
            </ItemTemplate>

        </asp:Repeater>

这就是它背后的代码：

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        BindRepeater();
    }
}
protected void rpt_ItemCommand(object source, RepeaterCommandEventArgs e)
{
    if (e.CommandName == "Delete") {
        int id = Convert.ToInt32(e.CommandArgument);
        deleteKlag(id);
    }
}
void deleteKlag(int id)
{
    SqlConnection sqlcn = new SqlConnection(@"data source=(LocalDB)\v11.0;attachdbfilename=|DataDirectory|\Database.mdf;integrated security=True;multipleactiveresultsets=True;application name=EntityFramework");
    SqlCommand sqlcm = new SqlCommand("DELETE FROM [Table] WHERE [Id] = @Id", sqlcn);
    sqlcm.Parameters.AddWithValue("@Id", id);
    if (sqlcn.State == ConnectionState.Closed)
    {
        sqlcn.Open();
    }
    sqlcm.ExecuteNonQuery();
    sqlcn.Close();
    BindRepeater();
}
protected void BindRepeater()
{
    SqlConnection con = new SqlConnection(@"data source=(LocalDB)\v11.0;attachdbfilename=|DataDirectory|\Database.mdf;integrated security=True;multipleactiveresultsets=True;application name=EntityFramework");
    string command = "Select * from [Table]";
    SqlCommand cmd = new SqlCommand(command, con);
    if (con.State == ConnectionState.Closed)
    {
        con.Open();
    }
    Repeater1.DataSource = cmd.ExecuteReader();
    Repeater1.DataBind();
}

它显示数据库中的所有项目都很好，但是当我按下“删除”按钮时没有任何反应。我尝试了很多不同的变化，但它们最终都无所作为。有什么想法吗？

啊，啊，我忘了把

OnItemCommand="rpt_ItemCommand"

在我的Repeater标签上

无法从转发器
