读一个中继器内的文本框 [英] read textbox inside a repeater

问题描述

我有2个中继器打印菜单标题和菜单项 - 在其他中。
他们看起来是这样的：

I have 2 repeaters that print menu headers and menu items - on inside the other. They look like this:

<asp:Repeater ID="ParentRepeater" runat="server" OnItemDataBound="ParentRepeater_ItemDataBound">
        <ItemTemplate>
            <h2>
                <%#DataBinder.Eval(Container.DataItem, "typenavn") %></h2>
            <asp:HiddenField ID="HiddenField1" Value='<%# Eval("id") %>' runat="server" />
            <asp:Repeater ID="ChildRepeater" runat="server">
                <ItemTemplate>
                    <table>
                        <tr>
                            <td style="width: 200px">
                                <%#DataBinder.Eval(Container.DataItem, "productName") %>
                            </td>
                            <td style="width: 200px">
                                <%#DataBinder.Eval(Container.DataItem, "pris") %>
                            </td>
                            <td>
                                <asp:HiddenField ID="HiddenField2" runat="server" />
                                <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox><br />
                            </td>
                        </tr>
                    </table>
                </ItemTemplate>
            </asp:Repeater>
        </ItemTemplate>
    </asp:Repeater>

这一切都很好，有趣和作品。
但现在我需要找到不同的文本框 - 在文本框可以写多少你想不同的菜单项。
我已经尝试了许多不同的事情：

It's all good and fun and works. But now I need to find the different textboxes - in the textboxes you can write how many of the different menu items you want. I have tried many different things:

Control myControl1 = FindControl("MainContent_ParentRepeater_ChildRepeater_0_HB1_0");

和这样的：

foreach (RepeaterItem item in ParentRepeater.Items)
{
    if (item.ItemType == ListItemType.Item)
    {
        TextBox txt = (TextBox)item.FindControl(("MainContent_ParentRepeater_ChildRepeater_0_HB1_0")) as TextBox;
        // do something with "myTextBox.Text"
        break;
    }
}

和这样的：

foreach (RepeaterItem item1 in ParentRepeater.Items)
{
    if (item1.ItemType == ListItemType.Item || item1.ItemType == ListItemType.AlternatingItem)
    {
        ChildRepeater = (Repeater)item1.FindControl("ChildRepeater");

        foreach (RepeaterItem item2 in ChildRepeater.Items)
        {
            if (item2.ItemType == ListItemType.Item || item2.ItemType == ListItemType.AlternatingItem)
            {
                TextBox txt = (TextBox)item2.FindControl(("ct100$MainContent$ParentRepeater$ct100$ChildRepeater$ct100$HB1")) as TextBox; // MainContent_ParentRepeater_ChildRepeater_0_HB

             }
         }
     }
     break;
 }

和它没有一个工作。有人在那里可以帮助我吗？如何让我的中继器??

And none of it work. Can anybody out there help me?? How do I get hold of my textbox inside the repeater??

推荐答案

的的FindControl 功能应采取的服务器的控件的ID，而不是呈现的客户端的控制。你应该能够做到这一点：

The FindControl function should take the ID of the server control, not the rendered client control. You should be able to do this:

var txt = item.FindControl("TextBox1") as TextBox;
if (txt != null) 
{
    // found it!
}

要调整code：

foreach (RepeaterItem item1 in ParentRepeater.Items)
{
    if (item1.ItemType == ListItemType.Item || item1.ItemType == ListItemType.AlternatingItem)
    {
        ChildRepeater = (Repeater)item1.FindControl("ChildRepeater");

        foreach (RepeaterItem item2 in ChildRepeater.Items)
        {
            if (item2.ItemType == ListItemType.Item || item2.ItemType == ListItemType.AlternatingItem)
            {
                 TextBox txt = (TextBox)item2.FindControl(("TextBox1")) as TextBox;
            }
        }
    }
}
