ASP.NET全选或多选删除

在文件中要先拖入jQuery.js文件

 <script type="text/javascript" language="javascript">
//全选
        $(function() {
            $("#cbAll").click(function() {
                $('input[name="cb"]').attr("checked", this.checked);
            });
            var $cb = $("input[name='cb']");
            $cb.click(function() {
                $("#cbAll").attr("checked", $cb.length == $("input[name='cb']:checked").length ? true : false);
            });
            var isCheched = $("#cbAll").attr("checked");
            var idStr = "";
            $("[name='cb']").each(function() {
                $(this).attr("checked", isCheched);
                idStr = idStr + "," + $(this).val();
            });
            $("#" + '<%=hfids.ClientID %>').val(idStr);
        });
//多选
        $(function() {
            $("[name='cb']").click(function() {
                var idStr = "";
                $("[name='cb']:checked").each(function() {
                    idStr = idStr + "," + $(this).val();
                });
                $("#" + '<%=hfids.ClientID %>').val(idStr);
            });
        });
    </script>

要重复的区域的多选框

分页旁边的选择框

<input type="checkbox" id="cbAll" />全选 //全选的复选框，勾选时是全选，不勾选时是全不选

<asp:LinkButton ID="lbtnAllDel" runat="server" OnClick="lbtnAllDel_Click">删除</asp:LinkButton> //LinkButton删除按钮

<asp:HiddenField ID="hfids" runat="server" /> //隐藏域用于存放选择的id值

多项选择删除后台事件

protected void lbtnAllDel_Click(object sender, EventArgs e)

{

string ids = hfids.Value; //1,2,3,4,5,6

string[] ss = ids.Split(','); //用,号隔开的数值 1 2 3 4 5 6

foreach (string str in ss)

{

int x;

if (int.TryParse(str,out x)) //当1 2 3 4 5 6 是数字存放于x中

{

new XiaobinShop.DAL.NewsDAO().Delete(x);

}

Xiaobin.Utility.Tool.AlertAndGo("删除成功",Request.Url.ToString(),this.Page);

}

直接后台方法

全选框

<asp:CheckBox ID="chkall" AutoPostBack="true" runat="server" oncheckedchanged="chkall_CheckedChanged" />

重复区域的的复选框

<asp:CheckBox ID="chk" ToolTip='<%#Eval("id") %>' runat="server" />

后台:

protected void chkall_CheckedChanged(object sender, EventArgs e)
        {
            CheckBox chk = (sender as CheckBox);
            if (chk.Checked)
            {
                foreach (RepeaterItem item in rep.Items)
                {
                    (item.FindControl("chk") as CheckBox).Checked = true;
                }
            }
            else
            {
                foreach (RepeaterItem item in rep.Items)
                {
                    (item.FindControl("chk") as CheckBox).Checked = false;
                }
            }

        }
删除事件  删除按钮在rep外面的
 protected void Button3_Click(object sender, EventArgs e)
        {
            foreach (RepeaterItem item in rep.Items)
            {
                CheckBox chk = item.FindControl("chk") as CheckBox;
                if (chk.Checked)
                {
                    dal.Delete(int.Parse(chk.ToolTip));
                }
            }
            Response.Redirect(Request.Url.ToString());
        }

编辑  编辑按钮在rep外面的
protected void btnMod_Click(object sender, EventArgs e)
        {
            hfoperate.Value = "edit";
            string id = "";
            foreach (RepeaterItem item in rep.Items)
            {
                CheckBox chk = item.FindControl("chk") as CheckBox;
                if (chk.Checked)
                {
                    id = chk.ToolTip;
                    break;
                }
            }
            if (id == "")
            {
                Xiaobin.Utility.Tool.Alert("请选择需要编辑的项。", this.Page);
                return;
            }
            Model.Class c = dal.GetModel(int.Parse(id));
            if (c != null)
            {
                txtclassname.Text = c.classname;
                hfid.Value = c.id.ToString();
                Xiaobin.Utility.Tool.ExecJS("$.popup.open('#pop')", this.Page);
            }
        }
