TestClick.aspx:


<form runat=server>
<asp:Button id="Button1" Text="Button1" runat=server onclick="Button1_Click" />
<asp:Button id="Button2" Text="Button2" runat=server onclick="Button2_Click" />
</form>
<script language=C# runat=server>

void Page_Load(object o, EventArgs e)
{
if (IsPostBack)
{
if (Request.Form[Button1.UniqueID] != null)
{
Response.Write("Page_Load: Button 1 clicked<BR>");
}
else if (Request.Form[Button2.UniqueID] != null)
{
Response.Write("Page_Load: Button2 clicked<BR>");
}
}
}

void Button1_Click(Object o, EventArgs e)
{
Response.Write("Button 1 clicked");
}

void Button2_Click(Object o, EventArgs e)
{
Response.Write("Button 2 clicked");
}

</script>

private void btn_Click(object sender,EventArgs e)
{
Button _btn=(Button)sender;
Response.Write("您所点击的按钮为"+_btn.ID.ToString());
}

判断Sender

[acewang]

事件里object sender,EventArgs e

判断这个（Button）Sender

[hyifeng]

上面的朋友看好了，楼主说在Page_Load中 ！

[tangcz]

（Button）object sender

if (Request.Form[YourButton1.UniqueID] != null)
{
//YourButton1 is clicked
}
else if (Request.Form[YourButton2.UniqueID] != null)
{
//YourButton2 is clicked
}

搂住都说了是在 load事件里判断啊？load的sender是Page对象，根本不知道是谁发送的，关注。。。

[delphi_bird]

UniqueID是什么意思啊？和ID有什么区别啊？

[wyc2000]

if page.ispost=isvalid then
.....
end if

查msdn咯

[BeyondLove2000]

页面的ID加上Button的ID=UniqueID

[LineCorner]

为什么我的Button的ID=UniqueID,而且Request.Form(MyButton1.UniqueID)=""
