ASP.NET全選或多選刪除

在文件中要先拖入jQuery.js文件

 <script type="text/javascript" language="javascript">
//全選
        $(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);
        });
//多選
        $(function() {
            $("[name='cb']").click(function() {
                var idStr = "";
                $("[name='cb']:checked").each(function() {
                    idStr = idStr + "," + $(this).val();
                });
                $("#" + '<%=hfids.ClientID %>').val(idStr);
            });
        });
    </script>

要重復的區域的多選框

分頁旁邊的選擇框

<input type="checkbox" id="cbAll" />全選 //全選的復選框，勾選時是全選，不勾選時是全不選

<asp:LinkButton ID="lbtnAllDel" runat="server" OnClick="lbtnAllDel_Click">刪除</asp:LinkButton> //LinkButton刪除按鈕

<asp:HiddenField ID="hfids" runat="server" /> //隱藏域用于存放選擇的id值

多項選擇刪除后臺事件

protected void lbtnAllDel_Click(object sender, EventArgs e)

{

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

string[] ss = ids.Split(','); //用,號隔開的數值 1 2 3 4 5 6

foreach (string str in ss)

{

int x;

if (int.TryParse(str,out x)) //當1 2 3 4 5 6 是數字存放于x中

{

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

}

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

}

直接后臺方法

全選框

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

重復區域的的復選框

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

后臺:

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;
                }
            }

        }
刪除事件  刪除按鈕在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());
        }

編輯  編輯按鈕在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("請選擇需要編輯的項。", 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);
            }
        }
