I have a general question of how to do this?

I have a webpage with 5 buttons and a 1 text box. The idea is if I click on
any of the buttons a text should appear in the text box related to the
button.
My question is what is the best way to program this?

I tried to use AJAX and update panel, but it's too slow, when I click on the
button it takes 1 or 2 seconds to display the text, long enough for user to
wonder what's going on and click on the button again or click on something
else.

Should I use hidden field for each button (with JavaScript) and move the
text from the hidden field in to the Text box when user clicks on a button?
Should I use 5 hidden text boxes and show / hide them when user clicks on a
button?

Which one is the most efficient?

Should I use ASP.NET buttons or HTML buttons or something else?

Or is there a better way to do this?

Thank You

Peter

Re: How to develop

Hi,,

if you want to no delay... javascript is good since all happens in
client side...

Best of luck

RE: How to develop

Hi Peter,

I agree with Munna that using pure client-side script to do the message
displaying task is preferred(if the messages can be statically determined
after page render ) and postback or AJAX is unnecessary. here is very
simple page to demonstrate the javascript approach:

# I used a statically defined javascript array, for your scenario, you can
also use Page.ClientScript.RegisterXXX method to emit such a client script
variable in codebehind(such as from some database records...):
===============================
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Untitled Page</title>
<script type="text/javascript">

var messages = new
Array("message1","message2","message3","message4", "message5");

function display_message(index)
{
alert(messages[index]);
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>

<asp:TextBox ID="txtMessage" runat="server"></asp:TextBox>
<br />
<asp:Button ID="Button1" runat="server" Text="Button1"
OnClientClick="display_message(0);" />
<asp:Button ID="Button2" runat="server" Text="Button2"
OnClientClick="display_message(1);" />
<asp:Button ID="Button3" runat="server" Text="Button3"
OnClientClick="display_message(2);" />
<asp:Button ID="Button4" runat="server" Text="Button4"
OnClientClick="display_message(3);" />
<asp:Button ID="Button5" runat="server" Text="Button5"
OnClientClick="display_message(4);" />

</div>
</form>
</body>
</html>

================================

Hope this helps.

Sincerely,

Steven Cheng
