如何取得repeater里面控件的值

Question

<asp:Repeater ID="rp1" runat="server" OnItemDataBound="rp1_ItemDataBound">
            <ItemTemplate>
                <asp:Repeater ID="rp2" runat="server" OnItemDataBound="rp2_ItemDataBound">
                    <ItemTemplate>
                        <asp:TextBox ID="txt1" runat="server" Width="690px" Height="50px" TextMode="MultiLine"></asp:TextBox>
                        <asp:Repeater ID="rp3" runat="server">
                            <ItemTemplate>
                                <asp:TextBox ID="txt2" runat="server" Width="690px" Height="50px" TextMode="MultiLine"></asp:TextBox>
                            </ItemTemplate>
                        </asp:Repeater>
                    </ItemTemplate>
                </asp:Repeater>
            </ItemTemplate>
        </asp:Repeater>
在sendbtn_Click事件里如何才能取到txt1及txt2的值.

Answer 1

 Button button = sender as Button;
        RepeaterItem item = button.Parent as RepeaterItem;
        TextBox tt = item.FindControl("txt1") as TextBox ;
        Response.Write("<script>alert('"+tt.Text+"');</script>");

Answer 2

要循环遍历吧  rp1.rows[i].findcontrol("txt1")  as TextBox

Answer 3

sendbtn这个按扭是repeater以外的,不是包含在里面的<asp:Repeater ID="rp1" runat="server" OnItemDataBound="rp1_ItemDataBound">
            <ItemTemplate>
                <asp:Repeater ID="rp2" runat="server" OnItemDataBound="rp2_ItemDataBound">
                    <ItemTemplate>
                        <asp:TextBox ID="txt1" runat="server" Width="690px" Height="50px" TextMode="MultiLine"></asp:TextBox>
                        <asp:Repeater ID="rp3" runat="server">
                            <ItemTemplate>
                                <asp:TextBox ID="txt2" runat="server" Width="690px" Height="50px" TextMode="MultiLine"></asp:TextBox>
                            </ItemTemplate>
                        </asp:Repeater>
                    </ItemTemplate>
                </asp:Repeater>
            </ItemTemplate>
        </asp:Repeater>
<asp:Button ID="sendbtn" runat="server" Text="提交" OnClick="sendbtn_Click" />

Answer 4

protected void rp1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
    if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
    {
        DataRowView drView = (DataRowView)e.Item.DataItem;
        string txt1Value =drView["txt1"].ToString();//得到ID为txt1输入框Text
    }
}
原理就是这样

Answer 5

Repeater rept3 = (Repeater)e.Item.FindControl("rp3");加上这句得到嵌套在rp1里的Repeater控件

Answer 6

貌似这是Repeater三重嵌套  。。

Answer 7

  if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            string au_id = ((DataRowView)e.Item.DataItem).Row["au_id"].ToString();
            Repeater repeaterSub = (Repeater)e.Item.FindControl("repeaterSub");
            }
        }多层嵌套同理。

Answer 8

ASP.NET的几个主要数据绑定控件都有FindControl();方法，遍历里面的控件
