在aspx页面中的

这样做..

<如果您有任何服务器端处理，则需要
....

in aspx page do this..

if you have any server side processing....

<asp:textbox id="txtNotOver3" runat="server" autopostback="True" ontextchanged="txtNotOver2_TextChanged" >

如果没有服务器端/数据库交互使用javascript ...

if no server side/database interaction use javascript...

<asp:textbox id="txtNotOver3" runat="server" >
<asp:textbox id="txtNotOver2" runat="server" >

page_load event

on page_load event

txtNotOver3.Attributes.Add("onblur","ManipulateValue(this)")

并在aspx页面的javascript中处理它

and handle it in javascript in aspx page

<script language="javascript">
function ManipulateValue(txt)
{
your code
}
</script>

如果有，请告诉我帮助..

let me know if it helps..

为什么不尝试下面给出的例子？

Why don''t you try something like the example given below?

protected void FunctionOne()
{
//Your stuff
}
protected void FunctionTwo()
{
//Your stuff
}
protected void FunctionThree()
{
//Your stuff
}
protected void txtNotOver1_TextChanged(object sender, EventArgs e)
{ 
FunctionOne(); 
FunctionTwo();
}
protected void txtNotOver2_TextChanged(object sender, EventArgs e)
{ 
FunctionTwo();      
}
protected void txtNotOver3_TextChanged(object sender, EventArgs e)
{
FunctionThree();
FunctionTwo();      
}
protected void Button1_Click(object sender, EventArgs e)
{
FunctionTwo();      
}
