gridview取值的問題?

Question

我的想法是：在gridview的編輯狀態下，點某列中的一按鈕，彈出一個層，然後將層中的某值賦給gridview中的TextBox,我試了很久，都沒有成功，請大家指導...謝謝!!

Answer 3

你的這種方法，不能實現我的要求。
但還是很感謝，我的想要的是:在gridview同一列模板中，有一個textbox，和一個button控件，我希望在我點button處發click事件後，彈出一個層,然後點層中的一button按鈕把層中的某值寫入到該模板列中的textboxt。主要實現的是這個功能謝謝

Answer 4

 楼上的跟LZ问的好像挂不上沟哦？？？
LZ分步骤来解答：
1.单击GrdiView某个按钮就弹出一个层。这个可以用js来控制层的显示隐藏。这个div  LZ可以在那个页面提前设计好。调用的时候就控制居中显示就行。
2.层中的某个控件的值传递到GridView的那个编辑TextBox框，这个不会。难在于如何获取到这个TextBox的ID，如果可以获取的话。那就可以通过js来给值

Answer 5

AJAX吧POPO控件完全满足你的需求给你个例子
 <asp:Repeater ID="rptServerSearch" runat="server" OnItemCommand="rptServerSearch_ItemCommand">
                                 <ItemTemplate>
                                <div class="row">
                                <div class="input">
                                   <asp:CheckBox ID="cbxSonger" runat="server"/>
                                </div>
                                <input type="hidden" name="songer" id="songer" value="<%#Eval("url") %>|<%#Eval("lrc") %>" />
                                <asp:HiddenField id="songerser" runat="server" value='<%#Eval("url") %> ' />
                                    <asp:HiddenField id="songers" runat="server" value='<%#Eval("lrc") %>' />
                                    <asp:HiddenField id="titles" runat="server" value='<%#Eval("title") %>' />
                                <div class="name">
                                    <asp:LinkButton ID="lbtPlay" CssClass="songname_font" CommandName="Play" runat="server">
                                        <asp:Label ID="lblMusicName" runat="server" Text='<%#Eval("title")%>'></asp:Label>
                                    </asp:LinkButton>
                                </div>
                                <div class="songer"><asp:Label ID="lblSinger" runat="server" Text='<%#Eval("singer") %>'></asp:Label></div>
                                <div class="save">
                                    <asp:LinkButton ID="lbtSaveMusic" CommandName="save" runat="server">保存</asp:LinkButton></div>
                                    
                                    <ajaxToolkit:ConfirmButtonExtender ID="ConfirmButtonExtender1" runat="server" 
                                        TargetControlID="lbtSaveMusic" 
                                        DisplayModalPopupID="ModalPopupExtender1">
                                        </ajaxToolkit:ConfirmButtonExtender>
                                        <ajaxToolkit:ModalPopupExtender ID="ModalPopupExtender1" runat="server" 
                                            TargetControlID="lbtSaveMusic" 
                                            PopupControlID="pnlSaveMusic" 
                                            OkControlID="btnAddOk" 
                                            CancelControlID="btnAddCl" 
                                            BackgroundCssClass="modalBackground" /> 
                                </div>
                                </ItemTemplate>
                        </asp:Repeater>

Answer 6

楼主可以考虑用Gridview+detailsview
不要用弹出了　！

Answer 7

"难在于如何获取到这个TextBox的ID"
我現在就嚓在這，不知如何取得其id!!!

Answer 8

ajax我用的比較少，
我現在最想知道的是：我的這種想法現實嗎？能不能實現

Answer 9

你在生成GRIDVIEW的时候,对TEXTBOX的ID号生成要有规律.
同一行点击的那个赋值按钮,在生成行时,对赋值按钮的onclick属性设置函数,规律对应TEXTBOX的ID生成.
这样你执行同一行的赋值时,就能取到对应的TEXTBOX的ID号了
