Question

我在嵌套转发器中从文本框中获取新值时遇到问题。如果我在Text属性中键入静态值，如下所示：我可以获取值，但不能获取新值。

<ItemTemplate>
    <tr>
        <td width="160">
            <%# Eval("index")%>
        </td>
        <td>
            <%# Eval("Sex") %>
        </td>
        <td align="right">
            <button id="EditPuppy" class="open-dialog" runat="server">
                Rediger hvalp</button>
            <juice:Button TargetControlID="EditPuppy" runat="server" />
        </td>
        <td align="right" width="30">
            <asp:ImageButton runat="server" ID="DeletePuppy" CommandArgument='<%# Eval("dogid").ToString() %>'
                OnClientClick='return confirm("Er du sikker på at du gerne vil slette denne hvalp?")'
                OnCommand="DeletePuppy_Command" SkinID="DefaultDeleteButton" />
        </td>
    </tr>
    <div id="_Default" runat="server" class="basic-dialog" title="Basic dialog" runat="server">
        <asp:TextBox runat="server" ID="TextBoxPuppyName" Text="HEJ" /><!-- The textbox i am trying to get the value from -->
        <asp:Button UseSubmitBehavior="false" runat="server" ID="ButtonPuppyName" CommandArgument="<%# ((RepeaterItem)Container.Parent.Parent).ItemIndex %> <-- Getting parent repaterid"
            CommandName="<%# Container.ItemIndex %> <-- Getting current repeater index -->"
            OnCommand="ButtonPuppyName_Command" Text="Opdater" />
    </div>
    <juice:Dialog TargetControlID="_Default" AutoOpen="false" runat="server" />
</ItemTemplate>

Codebehind：

protected void ButtonPuppyName_Command(object sender, CommandEventArgs e) {
    int parentRepeaterItemIndex = Convert.ToInt32(e.CommandArgument);
    int childRepeaterItemIndex = Convert.ToInt32(e.CommandName);
    Repeater childReapter = (Repeater)RepeaterShowKuldUserList.Items[parentRepeaterItemIndex].FindControl("RepeaterShowKuldPuppyList");
    TextBox name = (TextBox)childReapter.Items[childRepeaterItemIndex].FindControl("TextBoxPuppyName");
    HttpContext.Current.Response.Write(name.Text);
}

感谢您的帮助！记住进入转发器工作是因为我可以获得“静态”值

我认为您的问题是您正在调用 repeater.DataBind （在页面加载？中）尝试添加！IsPostBack然后绑定您的数据......

其他选项是viewState = false ..它应该是“true”

希望有所帮助，然

在对话框中获取嵌套转发器内的值
