一、asp:Repeater
Repeater 控件用于显示被绑定在该控件上的项目的重复列表。Repeater 控件可被绑定到数据库表、XML 文件或者其他项目列表。
1.1-前台页面代码
<asp:Repeater ID="ImageTypeListNew" runat="server" OnItemCommand="ImageTypeListNew_ItemCommand"> <HeaderTemplate> <table cellspacing="0" border="0" id="ctl00_contentHolder_ImageTypeList" class="table table-striped"> <tbody> <tr> <th>分类名称</th> <th>图片数</th> <th>排序</th> <th style="width: 20%;">操作</th> </tr> </HeaderTemplate> <ItemTemplate> <tr> <td> <asp:HiddenField ID="hfItemIndex" runat="server" Value='<%#Container.ItemIndex %>' /> <asp:HiddenField ID="hfCategoryId" runat="server" Value='<%#Eval("CategoryId") %>' /> <Hi:HtmlDecodeTextBox ID="ImageTypeName" runat="server" Text='<%# Bind("CategoryName") %>' CssClass="forminput form-control" Visible='<%#Eval("CategoryId").ToString()!="0" %>' /> <asp:Label ID="ltlTypeName" runat="server" Text='<%# Bind("CategoryName") %>' Visible='<%#Eval("CategoryId").ToString()=="0" %>'></asp:Label> </td> <td> <%#Eval("VideoCounts") %> </td> <td> <asp:Label ID="Label1" runat="server" Text='<%# Bind("DisplaySequence") %>' Visible='<%#Eval("CategoryId").ToString()=="0" %>'></asp:Label> <asp:TextBox ID="txtDisplaySequence" runat="server" Button="btnSearchButton" CssClass="forminput form-control" value='<%# Eval("DisplaySequence") %>' Visible='<%#Eval("CategoryId").ToString()!="0" %>' onkeyup="this.value=this.value.replace(/D/g,'')" style="width: 60px;" onafterpaste="this.value=this.value.replace(/D/g,'')" /> </td> <td><span class="submit_shanchu"> <Hi:ImageLinkButton runat="server" ID="lkbtnDelete" CommandName="Delete" IsShow="true" Text="删除" Visible='<%#Eval("CategoryId").ToString()!="0" %>'/></span></td> </tr> </ItemTemplate> <FooterTemplate></tbody></table></FooterTemplate> </asp:Repeater>
1.2-后台页面代码(核心)
代码示例:
DataTable videoCategories = GalleryHelper.GetVideoCategories(0); DataRow row = videoCategories.NewRow(); //如果数据为空,设置第一行数据 row["CategoryId"] = "0"; row["CategoryName"] = "默认分类"; row["DisplaySequence"] = "0"; row["VideoCounts"] = "0"; videoCategories.Rows.InsertAt(row, 0); this.ImageTypeListNew.DataSource = videoCategories; this.ImageTypeListNew.DataBind();
1.3-使用方法
在页面加载时【Page_Load】可调用,以及删除/排序/编辑等场景也可调用。
二、UI:Grid/GridView
显示表格数据是软件开发中的一个周期性任务。ASP.NET 提供了许多工具来在网格中显示表格数据,例如 GridView 控件。通过使用 GridView 控件,您可以显示、编辑和删除多种不同的数据源(例如数据库、XML 文件和公开数据的业务对象)中的数据。
1.1-前台页面代码
<UI:Grid ID="grdTopCategries" DataKeyNames="CategoryId" runat="server" ShowHeader="true" AutoGenerateColumns="false" CssClass="table table-striped" GridLines="None" Width="100%"> <Columns> <asp:TemplateField HeaderText="分类名称"> <ItemTemplate> <span class="icon" categoryid='<%# Eval("CategoryId") %>' parentid='<%# Eval("ParentCategoryId") %>' id="spShowImage" runat="server"> <img src="../images/jian.gif" alt="ASP.NET WebForm中asp:Repeater和UI:Grid数据为空时如何显示表头?" width="24" height="24" /></span> <span class="Name" id="spCategoryName"><a href='<%# "/product_detail/"+Eval("CategoryId")%>' target="_blank"> <asp:Literal ID="lblCategoryName" runat="server" /></a></span> </ItemTemplate> </asp:TemplateField> <asp:BoundField HeaderText="URL重写名称" DataField="RewriteName" /> <asp:TemplateField HeaderText="排序"> <ItemTemplate> <asp:TextBox ID="txtSequence" CssClass="form-control" runat="server" Text='<%# Eval("DisplaySequence") %>' Width="80px" /> </ItemTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="操作" HeaderStyle-CssClass="td_left td_right_fff"> <ItemTemplate> <div class="operation"> <span><a href="javascript:ShowRemoveProduct(<%#Eval("CategoryId") %>)">转移商品</a></span> <span><span><a href="javascript:void(0);" onclick="javascript:CollectionCategory('<%# "EditReleteCategory.aspx?ParentCategoryId="+Eval("ParentCategoryId") + "&CategoryId="+Eval("CategoryId")%>')">相关课程</a></span></span> <span> <asp:HyperLink ID="lkEdit" runat="server" Text="编辑" NavigateUrl='<%# "EditActivityCategory.aspx?CategoryId="+Eval("CategoryId")%>'></asp:HyperLink> </span> </div> </ItemTemplate> </asp:TemplateField> </Columns> </UI:Grid>
1.2-后台页面代码(核心)
代码示例:
DataTable dt = new DataTable(); if (inviteCodeList.TotalRecords == 0) { dt.Columns.Add("SaleId"); dt.Columns.Add("UserId"); dt.Columns.Add("TransactionDate"); dt.Columns.Add("IncomeType"); dt.Columns.Add("TransactionNo"); dt.Columns.Add("TransactionType"); dt.Columns.Add("RefundId"); dt.Columns.Add("SaleName"); dt.Columns.Add("UserName"); dt.Columns.Add("OrderType"); dt.Columns.Add("PaymentType"); dt.Columns.Add("DeliverPrincipal"); dt.Columns.Add("CommissionRate"); dt.Columns.Add("Tax"); dt.Columns.Add("DeliverIncome"); dt.Columns.Add("ApprovedStatus"); dt.Columns.Add("Reason"); dt.Columns.Add("SettlementId"); dt.Columns.Add("Amount"); dt.Columns.Add("ApprovedStatusId"); if (dt.Rows.Count == 0) { dt.Rows.Add(dt.NewRow()); } this.grdSaleInviteCode.DataSource = dt; this.grdSaleInviteCode.DataBind(); }
