1.页面代码
如果要分页,那么页面开头必须写(<%@ Register Src="~/Controls/Page.ascx" TagName="Page" TagPrefix="uc1" %>)
并且分页,页脚<uc1:Page ID="Page2" runat="server" /> 前面的uc1要跟上面的TagPrefix值一样
<table class="table" id="gv">
<%--头标--%>
<thead>
<tr>
<td width="50px" class="auto-style1">
<asp:LinkButton ID="LinkButton1" runat="server" OnClick="DeleteByChk" OnClientClick="javascript:return checkValues('您确定要批量删除数据吗?')">删除</asp:LinkButton>
<input type="checkbox" name="ckb" class="checkall"/>
</td>
<td width="50px" class="auto-style1"><span style="margin-left:20px;">序</span></td>
<td width="100px" class="auto-style1">制单日期</td>
<td width="50px" class="auto-style1">订单状态</td>
<td width="250px" class="auto-style1">任务名称</td>
<td width="50px" class="auto-style1">销售编号</td>
<td width="50px" class="auto-style1">合同编号</td>
<td width="50px" class="auto-style1">客户名称</td>
<td width="50px" class="auto-style1">联系人</td>
<td width="50px" class="auto-style1">联系电话</td>
<td width="50px" class="auto-style1">管理</td>
</tr>
</thead>
<%--数据的绑定--%>
<asp:Repeater runat="server" ID="rpt">
<ItemTemplate>
<tr>
<td><input runat="server" id="chk" type="checkbox" value='<%#Eval("SId")%>' class="checkdelete"/></td>
<td><span style="margin-left:20px;"><%# Container.ItemIndex+1 %></span></td>
<td><span style="margin-left:25px;"><%#Eval("SOperDate")%></span></td>
<td><span style="margin-left:25px;"><%#Eval("SIsLock")%></span></td>
<td><span style="margin-left:25px;"><%#Eval("SName")%></span></td>

<td><span style="margin-left:25px;"><%#Eval("STell")%></span></td>
<td class="manage">
<a href="TaskInterManage.aspx?SId=<%#Eval("SId") %>" class="show">编辑</a>
<asp:LinkButton runat="server" ID="lb_del" class="delete" title="你确定要删除这一项吗?" OnClick="Delete" >删除</asp:LinkButton>
</td>
</tr>
</ItemTemplate>
</asp:Repeater>
</table>
<%--分页,页脚--%>
<table class="table">
<tr>
<td class="page">
<span style="float:left;" id="num" runat="server"></span>
<uc1:Page ID="Page2" runat="server" /> </td>
</tr>
</table>
2.数据的展示
private void show()
{
DataTable dt = System_Project_TasksBLL.GetList("");
//分页
int pageNumber = ;//页数
int pageSize = ;//每一页显示数 //判断是否需要分页
if (!string.IsNullOrEmpty(Request.QueryString["page"]))
pageNumber = Convert.ToInt32(Request.QueryString["page"]);
//把datatable类型的数据转换为list集合类型的数据
List<System_Project_Tasks> list = new List<System_Project_Tasks>();
foreach (DataRow item in dt.Rows)
{
System_Project_Tasks data = new System_Project_Tasks();
data.SId = Convert.ToInt32(item["SId"].ToString());
data.SOperDate = Convert.ToDateTime(item["SOperDate"].ToString());
data.SIsLock = int.Parse(item["SIsLock"].ToString());
data.SName = item["SName"].ToString();
data.SCode = item["SCode"].ToString();
data.SConNo = item["SConNo"].ToString();
data.SComId = item["SComId"].ToString();
data.SLinkMan = item["SLinkMan"].ToString();
data.STell = item["STell"].ToString();
list.Add(data);
}
//筛选要显示的数据
PagedDataSource pageDataSource = new PagedDataSource()
{
DataSource = list,//数据源
AllowPaging = true,//是否开启分页
PageSize = pageSize,//每一页显示数
CurrentPageIndex = pageNumber,//开始页的位置
};
//下脚的分页菜单的制作,pageNumber:当前页面的页数 pageDataSource.PageCount:获取数据一共有多少页
this.Page2.sty("meneame", pageNumber, pageDataSource.PageCount, "?page=");
//赋值
this.num.InnerHtml = string.Concat("当前总计 - <span style='color:#ff0000; font-weight:bold;'>",dt.Rows.Count , "</span>条-数据");
this.rpt.DataSource = pageDataSource;
this.rpt.DataBind();
}
3.对控件的一些基本操作
protected void Delete(object sender, EventArgs e)
{
//查找此控件的上一个层级
RepeaterItem parent = (sender as LinkButton).Parent as RepeaterItem;
//在此层级下面查找控件(并不是找此层级的子集)
HtmlInputCheckBox htmlInputCheckBox = parent.FindControl("chk") as HtmlInputCheckBox;
//获取chekbox的value值(id)
int num = Convert.ToInt32(htmlInputCheckBox.Value);
//删除
if (bll.Delete(num))
{
string str = HttpContext.Current.Server.HtmlEncode("您好!工程测试单删除成功!");
Response.Redirect(string.Concat("/InfoTip/Operate_Success.aspx?returnpage=", base.Request.Url.AbsoluteUri, "&tip=", str));
}
} protected void DeleteByChk(object sender, EventArgs e)
{
//遍历Repeater每一行数据
foreach (RepeaterItem item in this.rpt.Items)
{
//获取每一行数据中的id叫chk的控件
HtmlInputCheckBox htmlInputCheckBox = item.FindControl("chk") as HtmlInputCheckBox;
//判断此行数据的checkbox有没有勾选上
if (!htmlInputCheckBox.Checked)
{
//如果没有,那么跳过此次循环
continue;
}
//获取id
int num = Convert.ToInt32(htmlInputCheckBox.Value);
//调用bll层方法删除
bll.Delete(num);
}
string str = HttpContext.Current.Server.HtmlEncode("您好!邮件已彻底删除!");
base.Response.Redirect(string.Concat("/InfoTip/Operate_Success.aspx?returnpage=", base.Request.Url.AbsoluteUri, "&tip=", str));
}
