Question

repeater
循环一个选项卡div
每个div内都有个CheckBoxList <asp:Repeater ID="rptrLanguageDivs" runat="server" OnItemDataBound="rptrLanguageDivs_ItemDataBound">
        <ItemTemplate>
            <div id="idTab_Info<%# Container.ItemIndex+2 %>" class="tab">
                <i>
                    <%=GetLocaleResourceString("Admin.Localizable.EmptyFieldNote")%></i>
                <asp:Label ID="lblLanguageId" runat="server" Text='<%#Eval("LanguageId") %>' Visible="false"></asp:Label>
                <table class="adminContent">
                    <tr>
                        <td class="adminTitle">
                            <nopCommerce:ToolTipLabel runat="server" ID="lblLocalizedAttributeName" Text="<% $NopResources:Admin.ProductVariantAttributeValues.New.Name %>"
                                ToolTip="<% $NopResources:Admin.ProductVariantAttributeValues.New.Name.Tooltip %>"
                                ToolTipImage="~/Administration/Common/ico-help.gif" />
                        </td>
                        <td class="adminData">
                           <%-- <asp:TextBox runat="server" CssClass="adminInput" ID="txtNewLocalizedName" />--%>
                            <asp:CheckBoxList ID="cbl_ProductAttributeValueList" runat="server" RepeatDirection="horizontal" >
                            </asp:CheckBoxList>
                        </td>
                    </tr>
                </table>
            </div>
        </ItemTemplate>
    </asp:Repeater>绑定 protected void rptrLanguageDivs_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {
            ProductVariantAttribute pva = ProductAttributeService.GetProductVariantAttributeById(this.ProductVariantAttributeId);
            int ProductAttributeId = 0;
            if (pva != null)
            {
               ProductAttributeId=pva.ProductAttributeId;
            }
            if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item)
            {
                Language lg = (Language)e.Item.DataItem;
                int LanguageID = lg.LanguageId;
                CheckBoxList ckb = (CheckBoxList)e.Item.FindControl("cbl_ProductAttributeValueList");
                ckb.DataSource = ProductAttributeService.GetProductAttributeValues(LanguageID, ProductAttributeId, null);
                ckb.DataTextField = "Name";
                ckb.DataValueField = "ProductAttributeValueID";
                ckb.DataBind();
            }
        }
在外部有个按钮
点击如何判断 必须有一个CheckBoxList内被打勾，并且只能存在一个CheckBoxList被打勾
并取值

Answer 1

很简单，你判读下，到底是那个Tab是正在使用状态，不就完事了。判读Tab的使用状态，不难吧!记得全部给分我。

Answer 2

我要是其中一个tab 打勾后切换到另外一耳光tab 打勾 
然后再提交呢？
分不是问题 问题是怎么解决这个问题

Answer 3

目前有个想法
就是选项卡的
 <div id="idTab_Info<%# Container.ItemIndex+2 %>" class="tab">
ID都是固定的  循环判断固定id下的checklistbox

Answer 4

遍历每一行，然后findcontrol~~~

Answer 5

foreach (RepeaterItem item in rep_user.Items)
            {
                CheckBox cb = (CheckBox)item.FindControl("cb_id");
                if (cb.Checked)
            }

Answer 6

    protected void Button1_Click(object sender, EventArgs e)
    {
        bool  = false;
        for (int i = 0; i < rptrLanguageDivs.Items.Count; i++)
        {
            CheckBoxList ckb = (CheckBoxList)rptrLanguageDivs.Items[i].FindControl("cbl_ProductAttributeValueList");
            if (-1 != ckb.SelectedIndex)
            {
                 = true;
            }
        }
        if ()
        {
            Response.Write("有选中");
        }
        else
        {
            Response.Write("无选中");
        }
    }

Answer 10

Js代码:
        function CheckList(obj) {
            obj.checked === true && $(".chkselect").not($(obj)).each(function () { $(this).get(0).checked = false; })
        }
Html代码:
<div id="idTab_Info2" class="tab" style="display: block;">
            <i>请注意，如果一个字段为空，标准字段将被使用.</i>
            <table class="adminContent">
                <tbody>
                    <tr>
                        <td class="adminTitle">
                            <span class="nop-tooltip">
                                <img id="ctl00_cph1_ctrlProductVariantAttributeValues_rptrLanguageDivs_ctl00_lblLocalizedAttributeName_imgToolTip"
                                    title="属性值的名称，例如'蓝'的颜色属性" src="Common/ico-help.gif" alt="?" style="border-width: 0px;">
                                <span id="ctl00_cph1_ctrlProductVariantAttributeValues_rptrLanguageDivs_ctl00_lblLocalizedAttributeName_lblValue"
                                    title="属性值的名称，例如'蓝'的颜色属性">名称</span> </span>
                        </td>
                        <td class="adminData">
                            <table id="ctl00_cph1_ctrlProductVariantAttributeValues_rptrLanguageDivs_ctl00_cbl_ProductAttributeValueList"
                                border="0">
                                <tbody>
                                    <tr>
                                        <td>
                                            <input id="ctl00_cph1_ctrlProductVariantAttributeValues_rptrLanguageDivs_ctl00_cbl_ProductAttributeValueList_0"
                                                type="checkbox" name="ctl00$cph1$ctrlProductVariantAttributeValues$rptrLanguageDivs$ctl00$cbl_ProductAttributeValueList$0"
                                                class="chkselect" onclick="CheckList(this)"><label for="ctl00_cph1_ctrlProductVariantAttributeValues_rptrLanguageDivs_ctl00_cbl_ProductAttributeValueList_0">赤</label>
                                        </td>
                                    </tr>
                                </tbody>
                            </table>
                        </td>
                    </tr>
                </tbody>
            </table>
        </div>
加了一个class= "chkselect" 加了一个onclick = "CheckList(this)"
