Highlited default key does not work. Can any one explain this ?

[Guest]

Thanks for taking the time to read this note

Can anyone explain what went wrong and any ideas how to fix it

I have a search page With three buttons few drop downs and a textbox. The search Button is the default button (because it is the first control in the HTML

When anything is entered into the text box the button is highlighted automatically. Hitting the enter key the event handler for this button btnSearch_click is executed. This worked fine for a few times and then something changed. Now it does not work

Here's what happens. When the button is highlighted by default (when a textpox gets focus and anything is entered)
hitting enter key nothing happens. I set break points and it does execute page load event so it posts the form back but does not execute the event btnSearch_click

When button is set to focus by tabbing to it (highlited by a dashed box) and hit the enter key, the event btnsearch_click executes

When the button is clicked with the mouse the event btnSearch_click executes

its a bug in IE. there are cases when hitting enter (depending on the mix of
controls), that it fail to post the button name, thus the o click does not
fire.

in your post back code, you can check if none of the buttons are in the
posted form data, then fire the click event your self.

if (this.IsPostBack)
{
bool buttonClicked = false;
foreach(string key in this.Request.Form.Keys)
{
if (string.Compare(key,"button1",true) == 0
&& (string.Compare(key,"button2",true) == 0
&& (string.Compare(key,"button3",true) == 0)
buttonClicked = true;
}

if (buttonClicked)
// do click i want
}
