在Page_Load里写 button.select应该行吧

不行。没有button.select，应该和accesskey有关。

有点糊涂， 你是不是说你按enter的时候， 相当于click那个button？偶很菜的。

You need to create a function and call it from in page_load or wherever you want:private void setFocus( System.Web.UI.Control ctrl )
{
string s = "<SCRIPT language='javascript'>document.getElementById('" + ctrl.ID + "').focus() </SCRIPT>";
this.RegisterStartupScript( "focus", s );
}

I think this focus will be lost after you input anything in the textbox.

you're right, if you want a button to become default button after entering something on the page, you have to do something else.

Make this button the first button in the form

it works.private void TextBox1_TextChanged(object sender, System.EventArgs e)
{
SetFocusControl("Button3");
}
public void SetFocusControl( String ControlName)
{
String script= @"<script language="+"\"javascript\"" + ">" + " var control = document.getElementById(\"" + ControlName + "\");" + " if( control != null ){control.focus();}" + "</script>";
Page.RegisterStartupScript("Focus", script);
}
