Repeater控件想必熟悉. web开发的人员是很了解不过的了，接下来将与大家共同学习下它的全选删除和分页，感兴趣的你可不要错过了哈，希望可以帮助到你
代码如下:
<script type="text/javascript">
function SelectAll(box)
{
for(var i=0;i <document.form1.elements.length;i++)
{
var e=document.form1.elements[i];
if((e.type=='checkbox'))
{
var o=e.name.lastIndexOf('cbx');
if(o!=-1)
{
e.checked=box.checked;
}
}
}
}
</script>
<body>
<form id="form1" runat="server">
<div>
</div>
<asp:Repeater ID="Repeater1" runat="server">
<HeaderTemplate>
<table>
<tr><th><input id= "chkHeader" type= "checkbox" onclick= "SelectAll(this)"/>全选</th><th>报到号</th><th>考生号</th><th>姓名</th><th>身份证号码</th><th>家庭地址</th><th>类别</th><th>专业</th></tr>
</HeaderTemplate>
<ItemTemplate>
<tr><td align="center" ><asp:CheckBox ID="cbx" runat="server" /></td><td><asp:Label id="lbl" Text='<%#Eval("id") %>' runat="server" ></asp:Label></td><td><%#Eval("ksh") %></td><td><%#Eval("xm") %></td><td><%#Eval("sfzh") %></td><td><%#Eval("jtdz") %></td><td><%#Eval("jhxzmc") %></td><td><%#Eval("lqzy") %></td></tr>
</ItemTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater>
<br />
<asp:Button ID="btnDel" runat="server" onclick="btnDel_Click" Text="批量删除" OnClientClick="return confirm('确定要删除吗？该操作不可恢复！！！')" />
<br />
<br />
<webdiyer:AspNetPager ID="benren" runat="server" pagesize="2"
CssClass="anpager" onpagechanged="AspNetPager1_PageChanged"
FirstPageText="首页" LastPageText="尾页" NextPageText="下一页" PrevPageText="上一页"
ShowMoreButtons="False" ShowPageIndexBox="Never" AlwaysShow="True">
</webdiyer:AspNetPager>
</form>
</body>
==================
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
string username = Session["username"].ToString();
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["shan"].ConnectionString);
conn.Open();
SqlCommand count = new SqlCommand("select count() from do.so where baosongren = '"+username+"'", conn);
benren.RecordCount = (int)count.ExecuteScalar();
conn.Close();
BindData();
}
}
public void BindData()
{
string username = Session["username"].ToString();
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["shnn"].ConnectionString);
string sql = "select from dao where baosongren = '"+username+"' order by ID desc";//这句在大型数据中应该用select 查询语句
SqlDataAdapter da = new SqlDataAdapter(sql, conn);
DataSet ds = new DataSet();
da.Fill(ds, benren.PageSize (benren.CurrentPageIndex - 1), benren.PageSize, "temptbl");
DataTable dt = ds.Tables["temptbl"];
Repeater1.DataSource = dt;
Repeater1.DataBind();
}
protected void AspNetPager1_PageChanged(object src, EventArgs e)
{
//AspNetPager1.CurrentPageIndex = e.NewPageIndex;
BindData();
}
protected void btnDel_Click(object sender, EventArgs e)
{
string delId = "";
//先遍历取得选中项
for (int i = 0; i < this.Repeater1.Items.Count; i++)
{
CheckBox cbx = (CheckBox)Repeater1.Items[i].FindControl("cbx");
Label lbl = (Label)Repeater1.Items[i].FindControl("lbl");
if (cbx != null)
{
if (cbx.Checked)
{
delId += lbl.Text + ",";
}
}
}
//去掉一个,
delId = (delId + ")").Replace(",)", "");
//Response.Write("删除的语句是delete news_sosuo8_ where id_news_ in(" + delId + ")");
//自己写删除语句吧
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["shann"].ConnectionString);
SqlCommand del = new SqlCommand("delete so where id in(" + delId + ")", conn);
conn.Open();
int myupdate = del.ExecuteNonQuery();
conn.Close();
if (myupdate > 0)
{
Page.ClientScript.RegisterStartupScript(Page.GetType(), "message", "<script language='javascript'>alert('删除成功！');</script>");
}
BindData();
}
