获取Repeater里textbox的数据

Question

如何获取Repeater里的textbox的数据？

Answer 1

不行。((TextBox)Repeater1.FindControl("TextBox１")).Text，发生＂未将对象引用设置到对象的实例。＂错误．

Answer 2

                foreach (RepeaterItem var in this.Repeater.Items)
                {
                    if (var.ItemType != ListItemType.Header &&
                         var.ItemType != ListItemType.Footer)
                    {
                        TextBox box = var.FindControl("TextBox１") as TextBox;
                                            
                    }
                }判断下模板的类型

Answer 3

比如说ItemCommand事件中应判断e.ItemIndex>=0才执行下面的语句，否则，rp.FindControl("")取到的是null((TextBox)e.Item.FindControl("TextBox1")).Text

Answer 4

我是在 protected void LinkButton1_Click(object sender, EventArgs e)事件里面写的。  就是当按钮被点击的时候，获取Repeater1里面的TextBox1的数据。  

Answer 5

<form id="form1" runat="server">
    <div>
        
        <asp:Repeater ID="Repeater1" runat="server">
        <ItemTemplate>
        <asp:TextBox ID="TextBox1" runat="server" Text="123"></asp:TextBox>
        </ItemTemplate>
        </asp:Repeater>
        <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" /></div>
    </form>protected void Page_Load(object sender, EventArgs e)
    {
        DataTable dt = new DataTable();
        dt.Columns.Add("A");
        dt.Rows.Add(new string[] { "A" });
        this.Repeater1.DataSource = dt;
        this.Repeater1.DataBind();
    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        Response.Write(((TextBox)this.Repeater1.Items[0].FindControl("TextBox1")).Text);
    }
