通常情况下，ASP.Net 页面 PostBack（回发）后，页面一般定位在整个网页的顶部!但我们在实际项目中经常需要，回发后能定位到自己刚刚点击提交按钮位置，那这种情况如何实现呢，下面介绍三种实现些功能的方法
一、应用程序级设置：在web.config中增加一个pages节点
<pages maintainScrollPositionOnPostBack="true">
二、页面级设置：在aspx页面上进行设置,在页面的page指令中增加属性
<@page MaintainScrollPositionOnPostback="true"
三、在后台cs代码中设置

////////////////数据库取日期部分
获取SQL字符串中日期部分的语句 数据库Sql,VFP,Access
作者：数据库Sql,VFP,Access 浏览：386次 评论：0条
在SQL中，日期类型DateTime的默认格式就是yyyy-mm-dd hh:mi:ss: mmm，仍然大多数情况下我们只想得到它的日期部分，而不要后面的时间部分。
那么如何取得不包含时间的日期呢？比如要获取日期时间：2010-9-2 11:34:52中的2010-9-2，可使用如下方法。
只需要使用Convert()函数就足够了，下面是方法，希望对您有所帮助。
select convert(char(10),GetDate(),120) as Date
参数中的第3个参数就是用来设置日期类型数据的显示样式的，下面介绍几种样式的参数：
100：mm dd yyyy
101：mm/dd/yyyy
102：yyyy.mm.dd
103：dd/mm/yyyy
106：dd mm yyyy
108：hh:mi:ss(时间)
111：yyyy/mm/dd
112：yyyymmdd
120：yyyy-mm-dd
现在，我们应该明白了，用这种方法获得日期部分将会更加方便，与这种方法比较Datename()函数的好处就是在于得到日期的具体部分。
知识扩展：
比如，您想获取SQL数据库字段中的日期，可以这样来获取：
假如，SQL某数据表中有一个字段的名称是：MyDateTime
那么，我们就这样来获取：
select convert(char(10),MyDateTime,120) as MyDate from MyTable
当然，如何要想获取当天日期之前的数据，而不需要当前日期之后的数据，可以这样来获取：
select id,Aritle,convert(char(10),MyDateTime,120) as MyDate,FORMAT(Now(),'YYYY-MM-DD') as MyNowDate from MyTable where MyDate<=MyNowDate
这样，上述的语句功能，返回的是日期小于等于今天的记录；如果日期大于今天的记录，将不返回。

在Gridview或者Formview里面放置了其它的控件，比如label，那么如何获取这个label的值呢？看以下代码
前台GridView 的设置：
<asp:GridView ID="GridView1" runat="server" AllowPaging="True"
AllowSorting="True" AutoGenerateColumns="False" DataKeyNames="ID"
DataSourceID="LinqDataSource1">
<Columns>
<asp:BoundField DataField="ID" HeaderText="编号" InsertVisible="False"
ReadOnly="True" SortExpression="ID" />
<asp:BoundField DataField="fname" HeaderText="文件名" SortExpression="fname" />
<asp:TemplateField HeaderText="下载地址" SortExpression="furl">
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("furl") %>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("furl") %>'></asp:Label>
<asp:Button ID="downBtn" runat="server" Text="点击下载" onclick="downBtn_Click" />
<asp:Label ID="errLabel" runat="server" Text=""></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="addtime" HeaderText="添加时间"
SortExpression="addtime" />
</Columns>
</asp:GridView>
后台cs文件：
protected void downBtn_Click(object sender, EventArgs e)
{
//根据控件所在的行和列，再用 FindControl函数获取到该控件
Label furlLabel = (Label)GridView1.Rows[1].Cells[3].FindControl("Label1");
string fileName = furlLabel.Text;
this.DownLoadFile(fileName);
}
Formview里面获取就更加简单，直接使用 Label furlLabel = (Label)FormView1.FindControl("furlLabel");

1。统计所有性别为女的销售员的数量：
table.Compute("Count(*)","Sex=0");
2。统计所有销售员中年龄大于20岁的
table.Compute("Count(*)","Birthday<'"+today);//today为今天的日期字符串
3。统计销售产品的平均价格
table.Compute("Aver(Price)","true");
4。统计产品代码为1的产品销售数量：
table.Compute("Sum(Quantity)","ProID=1");
5。统计所有产品的销售总金额：
要统计总销售金额，由于table中不存在某项产品某个促销员销售的金额数据，但我们可以通过Quantity*Price来获得。比如：
table.Compute("Sum(Quantity*Price)","true");
这里一个问题是：DataTable的统计功能没有SqlServer强，这个统计是错误的，因为Compute的统计不具备Sum(Quantity*Price)这样数据的功能。那怎么办呢？
对于这样复杂数据的统计，我们可以在DataTable中创建一个新的字段来完成，比如Amount，同时设置该字段的Expression为Quantity*Price，这样我们就可以使用统计功能了：
table.Compute("Sum(Amount)","true");
以上都是计算每一列的合计，要添加一行求合计可以使用下面的方法：
System.Data.DataRow dataRow=dataSet.Tables[0].NewRow()
'假设你的DataSet为dataSet，表在索引0位置，同时假设你的所有字段都是可以求合计的。
System.DataRow dataRow ＝ new System.DataRow();
dataRow=DT.NewRow();
然后就是统计了：
int i ;
int fldCnt ;
fldCnt=DT.Cols.Count;
for( i=0 ;i< fldCnt-1;i++)
dataRow(i)=DT.Compute("Sum("+i.ToString()+")","true");
DT.Rows.Add(dataRow);
好了，大功告成。希望对大家有用。

{

d.Add(ta.Rows[i][2].ToString(), count);

//post方法：//不会报错；需要名明空间using System.Collections.Specialized;：特殊集合
//前面 Server.Transfer("a2aspx.aspx");

-------------------------------发布网站：
1.发布网站：发布到到一个文件夹
2.安装iis和asp.net4.0:
C:WindowsMicrosoft.NETFrameworkv4.0.30319>aspnet_regiis.exe -i
开始安装 ASP.NET (4.0.30319)。
3.添加网站，端口号设为：8000以上
4.默认文档：添加登录页面；
5.点击全网站：选择：isapi和cgi都设为允许；
6.应用程序池：全部勾经典，在asp.net v4.0classc高级设置，表示改为localSystem;
7.在asp图标，父级目录改为true;
需要注意：发布时，要在空文件夹内放上东西，否则会丢失的！；
放到服务器上时，先上传文件，之后进入服务器操作便可；

-------------------------添加水印效果
string str = "文字";
Font font = Font("宋体",30f); //字体，大小
Brush brush = Brushes.Red; //笔刷，颜色
PointF point = new PointF(10f,10f); //左上角位置
//文字格式

sf.FormatFlags = StringFormatFlags.DirectionVertical
Image image = Image.FromFile("C:\1.gif");
Graphics g = Graphics.FromImage(image);
g.DrawString(str,font,brush,point,sf);
images.Save("c:\1.gif");
-----------------------------查看表的触发器
select * from sys.triggers

---------------------------------------sql区分大小写
ALTER TABLE tb ALTER COLUMN colname nvarchar(100) COLLATE Chinese_PRC_CI_AS
从数据库Collate到存储过程到函数，各种方法都有，选择适合你的。
第一种：
ALTER TABLE tb ALTER COLUMN colname nvarchar(100)
COLLATE Chinese_PRC_CI_AS --不区分大小写 ALTER TABLE tb
ALTER COLUMN colname nvarchar(100) COLLATE Chinese_PRC_CS_AS --区分大小写
alter database 数据库 COLLATE Chinese_PRC_CS_AS

转发与跳转的区别
Server.Transfer and Response.Redirect
Server.Transfer（ASP 3.0 以上） 和 Response.Redirect 在以前的 ASP 中就存在了，Page.Navigate 是 ASP.NET Beta 1 提供的新功能，它们之间的区别在于：
1、 Server.Transfer - 用于把处理的控制权从一个页面转移到另一个页面，在转移的过程中，没有离开服务器，内部控件（如：request, session 等）的保存的信息不变，因此，你能从页面 A 跳到页面 B 而不会丢失页面 A 中收集的用户提交信息。此外，在转移的过程中，浏览器的 URL 栏不变。
2、Response.Redirect - 发送一个 HTTP 响应到客户端，告诉客户端跳转到一个新的页面，客户端再发送跳转请求到服务器。使用此方法时，将无法保存所有的内部控件数据，页面 A 跳转到页面 B，页面 B 将无法访问页面 A 中 Form 提交的数据。
3、Page.Navigate - Page.Navigate 实现的功能和 Response.Redirect 差不多，它实际上包括三个步骤：首先调用 Response.Redirect，其次依次卸载所有的控件，最后调用 Response.End。

//方法所在页面和方法名
url: "ajax2.aspx/get",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(data) {
//返回的数据用data.d获取内容
alert(data.d);
},
error: function(err) {
alert(err);
}
});
}
有参数的
function Button2_onclick() {
$.ajax({
type: "Post",
url: "ajax2.aspx/get1",
//方法传参的写法一定要对，str为形参的名字,str2为第二个形参的名字
data: "{'s':'aa','s1':'bb'}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(data) {
//返回的数据用data.d获取内容
alert(data.d);

});
