讨教刷新问题！
<asp:DropDownList ID= "DropDownList1 " runat= "server " Width= "337px " AutoPostBack= "True ">
<asp:ListItem> 你好！ </asp:ListItem>
<asp:ListItem> 是的！ </asp:ListItem>
</asp:DropDownList>
当DropDownList1发生SelectedIndexChanged事件时，把它的值放到TEXTBOX中，
可是这个事件每次都会要刷一下页面，这个问题应该怎么解决！
包括TEXTBOX的TextChanged事件等都会有这样的问题，应该怎么解决这个问题？
[解决办法]
是每次都会刷新，postback的
你可以用asp.net Ajax来解决不刷新的问题 http://ajax.asp.net/

var d=document.getElementById( "d ");
