在使用服务器端控件的情况下，不能在页面上直接使用在js中用confirm进行删除判断

操作方式：在页面放置两个删除按钮控件，一个是可见的，用于触发后台的confirm判断，一个是隐藏的真正删除按钮，

我们还需要一个隐藏控件，用于保存confirm的选择结果

源码如下：

aspx界面：

                    <cc2:DcjetButton UseSubmitBehavior="false" OnClick="btnDelete_Click" Text="删 除" runat="server"
                        ID="btnDelete" />

                    <!--隐藏控件存值-->
                    <cc2:DcjetButton UseSubmitBehavior="false" OnClick="btnHiddenDelete_Click" Width="0px"
                        Height="0px" ID="btnHiddenDelete" runat="server" />
                    <asp:HiddenField ID="hidField" runat="server" />
                    <asp:HiddenField ID="hidFieldOid" runat="server" />

后台：

/// <summary>
        /// 获取选中行的OID
        /// </summary>
        /// <returns></returns>
        private string GetSelectedOid()
        {
            string strOid = string.Empty;
            for (int i = 0; i < this.gvInfo.Rows.Count; i++)
            {
                CheckBox chk = (CheckBox)this.gvInfo.Rows[i].FindControl("chkSelected");
                if (chk.Checked == true)
                {
                    strOid += chk.ToolTip + "|";
                }
            }
            if (!string.IsNullOrEmpty(strOid))
            {
                strOid = strOid.Substring(0, strOid.Length - 1);
            }
            return strOid;
        }        
/// <summary>
        /// 删除弹框
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        protected void btnDelete_Click(object sender, EventArgs e)
        {
            strOid = GetSelectedOid();
            this.hidFieldOid.Value = strOid;
            if (string.IsNullOrEmpty(strOid))
            {
                ScriptManager.RegisterStartupScript(this, this.GetType(), "", "alert('请选择您要删除的[" + this.PageReportName + "]！');", true);
                return;
            }
            string js = string.Format("document.getElementById('{0}').value=confirm('确定要删除已选的记录?');document.getElementById('{1}').click();", this.hidField.ClientID, this.btnHiddenDelete.ClientID);
            ClientScript.RegisterStartupScript(GetType(), "confirm", js, true);
        }

        /// <summary>
        /// 真正的删除操作
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        protected void btnHiddenDelete_Click(object sender, EventArgs e)
        {
            if (bool.Parse(this.hidField.Value) == true)
            {
                strOid = this.hidFieldOid.Value;
                HbViewCostManageDao hbcDao = new HbViewCostManageDao(DataConstCm.PARA_PLAT_DB_TYPE, objPageParaMessage.CompanyDBConn);
                hbcDao.Delete(strOid);
                DataLoadInfo(GetModelInfo(), strSorting);
            }
        }
