一些简单的方法！！

checkBox全选

<script  type="text/javascript">
   function SelectAllCheckboxes(spanChk)
   {
     var oItem=spanChk.children;
     var theBox=(spanChk.type=="checkbox")?spanChk:spanChk.children.tiem[0];
     xState=theBox.checked;
     elm=theBox.form.elements;
     for(i=0;i<elm.length;i++)
     if(elm[i].type=="checkbox" && elm[i].id!=theBox.id)
     {
       if(elm[i].checked!=xState)
       elm[i].click();
     }
   }
</script>
<asp:CheckBox ID="CheckBox1" runat="server" type="checkbox" onclick="javascript:SelectAllCheckboxes(this);" />

   将gridview中的数据全部导出(包括分页)为excel文件

 protected void btnLoad_Click(object sender, EventArgs e)
 {
        Response.Clear();
        //可令中文文件名不为乱码
        Response.AppendHeader("Content-Disposition", "attachment; filename=" + System.Web.HttpUtility.UrlEncode    (this.Title, System.Text.Encoding.UTF8) + ".csv");
        Response.Charset = "GB2312";
        Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
        Response.ContentType = "application/ms-excel";
          for (int i = 1; i < GridView1.Columns.Count; i++)
        {
              Response.Write(GridView1.Columns[i].HeaderText + ",");
        }

              Response.Write("\r\n");

        DataView DefaultDataView = ds.Tables[0].DefaultView;
        int colCount = DefaultDataView.Table.Columns.Count;

        foreach (DataRowView rowView in DefaultDataView)
        {
            // Display the value in each item of the DataRowView
            for (int i = 0; i < colCount; i++)
            {
                string strvalue = rowView[i].ToString().Replace('\r', ' ').Replace('\n', ' ').Replace('\t', ' ').Replace(",", "，").Trim();
                Response.Write(strvalue + ",");
            }
            Response.Write("\r\n");
        }
        Response.End();
  }

所有的控件变成只读

public static void ControlReadOnly(Control c)
    {
        foreach (Control childControl in c.Controls)
        {
            if (childControl is TextBox)
                ((TextBox)childControl).ReadOnly = true;
            else
                ControlReadOnly(childControl);

            if (childControl is Button)
                ((Button)childControl).Enabled = false;
            else
                ControlReadOnly(childControl);

            if (childControl is DropDownList)
                ((DropDownList)childControl).Enabled = false;
            else
                ControlReadOnly(childControl);

            if (childControl is GridView)
                ((GridView)childControl).Enabled = false;
            else
                ControlReadOnly(childControl);

            if (childControl is RadioButton)
                ((RadioButton)childControl).Enabled = false;
            else
                ControlReadOnly(childControl);

            if (childControl is RadioButtonList)
                ((RadioButtonList)childControl).Enabled = false;
            else
                ControlReadOnly(childControl);

            if (childControl is CheckBox)
                ((CheckBox)childControl).Enabled = false;
            else
                ControlReadOnly(childControl);

            if (childControl is CheckBoxList)
                ((CheckBoxList)childControl).Enabled = false;
            else
                ControlReadOnly(childControl);
        }
    }

简单的连接处理方法

 public static Database db = DatabaseFactory.CreateDatabase("DatabaseConnectionString");

 public static bool Add(User d)
    {
        string sqlCommand = "insert into Users (UserName,password,StoreID,Phone,Email,RealName,UserTypeID) values('" + d.UserName + "','" + d.Password + "','" + d.StoreID + "','" + d.Phone + "','" + d.Email + "','" + d.RealName + "','" + d.TypeID + "')";
        DbCommand mydbCommand = db.GetSqlStringCommand(sqlCommand);
        int i = db.ExecuteNonQuery(mydbCommand);
        if (i == -1)
            return false;
        return true;
    }

弹出提示

Response.Write("<script>alert('操作失败，请检查数据的有效性')</script>");

传值
 string s_url;
 s_url = "ShowCustomerInfo.aspx?name=" + this.tbPhone0.Text.Trim();
 Response.Redirect(s_url);

取值
  
   string name = Request.QueryString["name"];

编码密码
 public  static string   MD5(string str)
  {
    return FormsAuthentication.HashPasswordForStoringInConfigFile(str, "MD5");
  } 

gridview中删除选定的记录！！

            users d = new users();
            User method = new User();

      foreach (GridViewRow aa in this.GridView1.Rows)
        {
            bool isCheck = ((CheckBox)aa.FindControl("aa")).Checked;
            if (isCheck)
            {
                d.getUserid = Convert.ToInt32(this.GridView1.DataKeys[aa.RowIndex]["ID"].ToString());
                if (method.delete(d))
                {
                    Response.Write("<script>alert('管理已删除！！')</script>");
                  
                }
                this.DataBind();
            }
        }

       

 
gridview中添加提示对话框！！

在DeleteText中添加如下语句

<div id="de" onclick="JavaScript:return confirm('确定删除吗？')">删除</div> 

   显示完提示信息后打开新的窗体

 public static void Show(string values,string PageURL)          
{
       HttpContext.Current.Response.Write("<script>alert('" + values + "');window.location.href='" + PageURL + "'</script>"); 
       HttpContext.Current.Response.End(); 
} 

将gridview中的记录变成超链接的同时，将绑定的记录带到指定的窗体，

然后在制定的窗体里调用Request.Params["article_title"]就可以获取到传过来的值！

   

 <Columns>
        <asp:HyperLinkField DataNavigateUrlFields="article_title" 
        DataNavigateUrlFormatString="~/Show_Information.aspx?article_title={0}" 
        HeaderText=标题 DataTextField="article_title" />
</Columns>   

 先绑定一列后，将他删除，直接复制此段代码，将要传的值的字段修改即可！！
