在ASP.NET里实现MessageBox

http://www.microsoft.com/india/msdn/articles/119.aspx?

ShowMessageAtStartup

This control is used to show message at startup of the page. For example, if you want to inform the user with some information using message box after the post back. Then you can use this control. This control has following two properties,

MessageText:	This property is used to set the Message which is showed in the message box.
Enabled:	This property is used for enabling or disabling this control depending upon the requirement.

This control is used to show alert message or confirm message box when the page is submitted. For example, when the user is pressing a button to delete a record. During that time, if you want to ask the user for confirmation. Then you can use this control. This control has following properties,

MessageText:	This property is used to set the Message which is showed in the message box.
Enabled:	This property is used for enabling or disabling this control depending upon the requirement.
IsConfirmMessage:	This property is used to mention whether it is confirmation message box or alert message box.
ConfirmMessagePassClientScript:	This property is used to mention the client side script which has to executed if the confirmation message return true. i.e. when users presses ok button. This property will be used only when isConfirmmessage property is set to true
ConfirmMessageFailClientScript:	This property is used to mention the client side script which has to executed if the confirmation message return false. i.e. when users presses cancel button. This property will be used only when isConfirmmessage property is set to true.

一个不错的代码编辑工具

ASP.NET

CrimSon Editer

http://www.crimsoneditor.com/
我用它因为它体积小启动迅速最大的优点是免费哦
支持许多常用代码的语法高亮显示.
可以在这里下载到C#的代码高亮显示文件

顺便发现一bug??

闲言碎语 Asp.net

在这个http://www.cnblogs.com/huobazi/archive/2004/02/09/1053.aspx 里有一句
a.col_img_group=@gid
被DotText当成mailto 自动加上了mailto连接

使网页中的元素可编辑

ASP.NET Asp.net Javascript HTML

在net_lover的文章里找到了答案.

http://www.csdn.net/Develop/Read_Article.asp?Id=4405

代码如下：
<HTML>
<HEAD>
</HEAD>
<BODY>
<DIV ID=“oDiv”>TEST—TEST—TEST 您可以在这里编辑文字！</DIV>
<SCRIPT>
<!–
oDiv.contentEditable = true;
// –>
