很急，Repeater3小问题！100分

Question

怎么获取到我当前选中的Repeater3中的那一行的值， 比如我要删除的时候，得获取当前行的ID 怎么弄？

Answer 1

可以吧ID数据绑定在 button 的 CommandArgument 属性上，
在后台 取出CommandArgument 的值，

Answer 2

你是利用checkbox批量删除还是利用表内的单个button进行单个删除？可以遍历Repeater3,利用findcotrol来进行操作

Answer 3

<asp:LinkButton ID="lnkDel" runat="server" CommandName="Del" CommandArgument='<%# Eval("ID") %>'删除</asp:LinkButton>protected void rpt_ItemCommand(object source, RepeaterCommandEventArgs e)
{
     if (e.CommandName == "Del")
     {     }
}

Answer 4

<asp:LinkButton ID="lnkDel" runat="server" CommandName="Del" CommandArgument='<%# Eval("ID") %>'删除</asp:LinkButton>protected void rpt_ItemCommand(object source, RepeaterCommandEventArgs e)
{
  if (e.CommandName == "Del")
  {  }
}

Answer 5

<asp:LinkButton ID="lnkDel" runat="server" CommandName="Del" CommandArgument='<%# Eval("ID") %>'删除</asp:LinkButton>protected void rpt_ItemCommand(object source, RepeaterCommandEventArgs e)
{
  if (e.CommandName == "Del")
  {  }
}

Answer 6

如果LZ嫌楼上的方法太麻烦   可以把这句话复制到 你删除控件的后面<asp:Label ID="lbl_Order_Id" Visible="False" Text='<%# Eval("ID")  %>' runat="server" />
后台调用Label lableText = (Label)Repeater1.Items[e.Item.ItemIndex].FindControl("lbl_Order_Id");
取值的时候直接取它的Text 就行了。
lableText.Text

Answer 7

没执行这一块?你删除按钮不在Repeater3里面?

Answer 8

你用一个lable放在前面
把ID传值给lable
再将lable设置为隐藏
你提取这行的ID就好办了啊

Answer 9

我贴下完整代码吧Html:
<div>
    
    <asp:Repeater ID="Repeater1" runat="server" DataMember="DefaultView" 
            DataSourceID="SqlDataSource1" onitemcommand="Repeater1_ItemCommand">
            <ItemTemplate>
                <asp:Label ID="Label1" runat="server" Text=<%# DataBinder.Eval(Container.DataItem, "ProductID")%>></asp:Label>
                <asp:Label ID="Label2" runat="server" Text=<%# DataBinder.Eval(Container.DataItem, "ProductName")%>></asp:Label>
                   
                <asp:LinkButton ID="LinkButton1" runat="server" CommandName="Del" CommandArgument=<%# Eval("ProductID") %> >LinkButton</asp:LinkButton>
                <br />  
            </ItemTemplate>
    </asp:Repeater>
        <asp:SqlDataSource ID="SqlDataSource1" runat="server" 
            ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>" 
            SelectCommand="SELECT [ProductID], [ProductName] FROM [Products]">
        </asp:SqlDataSource>
        <br />
        <asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button" />
    </div>
CS:protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
        {
            if (e.CommandName == "Del")
            {
                //e.CommandArgument就是ID的值，你可以根据这个删除数据库中的记录
            }
        }

 <asp:Repeater ID="Repeater3" runat="server" OnItemCommand="Repeater3_ItemCommand">
                        <ItemTemplate>

                                </td>
                            </tr>
                        </ItemTemplate>
                    </asp:Repeater>下面后台
 protected void Repeater3_ItemCommand(object source, RepeaterCommandEventArgs e)
    {
断点       if (e.Item.ItemIndex > 0)
        {
            if (e.CommandName.Equals("del"))
            {
                string aa = e.CommandArgument.ToString();
            }
        }
    } 没有进断点。。 为什么

Answer 11

if (e.Item.ItemIndex > 0)
点击第一个item。 index是0,不会继续执行了。
