asp.net - 从asp.net中的repeater控件获取数据绑定(bind)值

Question

作为我的问题的后续Looping through a repeater control to get values of Textbox in asp.net如果用户在文本框中输入了数量，我想从中继器控件中获取相应的 ProductID 值:

<asp:Repeater ID="rptRequestForm" runat="server">
                    <HeaderTemplate>
                            <table border="0" width="100%">
                                <tr>
                                    <td style="width:50%" class="TextFontBold"><asp:Label runat="server" ID="Label1" Text="Supply Name"></asp:Label></td>
                                    <td style="width:25%" class="TextFontBold"><asp:Label runat="server" ID="Label2" Text="Quantity"></asp:Label></td>
                                    <td style="width:25%" class="TextFontBold"><asp:Label runat="server" ID="Label3" Text="Price (ea.)"></asp:Label></td>
                                </tr>
                            </table>
                    </HeaderTemplate>
                        <ItemTemplate>
                            <table border="0" width="100%">
                                <tr>
                                    <td style="width:50%" class="TextFont"><asp:Label ID="lblProductName" Text="<%#Trim(Eval("Product_Title"))%>" ><%#Trim(Eval("Supplie_title"))%></asp:Label></td>
                                    <td style="width:25%"><asp:TextBox ID="txtBox" runat="server" Width="30%" onblur="Javascript:numberonly(this)"></asp:TextBox></td>
                                    <td style="width:25%" class="TextFont"><span><%#Trim(FormatCurrency(Eval("Price")))%></span></td>
                                </tr>
                            </table>
                        </ItemTemplate>
                    </asp:Repeater> 

我的代码隐藏是:

For Each item As RepeaterItem In rptRequestForm.Items
                txtField = item.FindControl("txtBox")
                If Not IsNothing(txtField) Then
                    j += 1
                    strText = strText & ", " & txtField.Text
                End If
Next

我正在使用 FindControl 循环遍历文本框(以查看用户是否输入了有效数量)。如何获取对应ProductID的值？

Answer 1

向 ItemTemplate 添加标签，如下所示:

<td style="width:50%" class="TextFont"><asp:Label ID="lblProductName" runat="server"><%#Trim(Eval("Product_Title"))%></asp:Label></td>

在后面的代码中，找到这样的内容:

foreach (RepeaterItem item in Repeater1.Items)
{
    TextBox txtField = (TextBox)item.FindControl("txtBox");

    //extract value from textbox
    int Quantity = Convert.ToInt32(((TextBox)item.FindControl("txtBox").Text);

    //extract the value from the label
    string productName = ((Label)item.FindControl("lblProductName")).Text;
}
