Button to not postback?

[Techno]

how is it possible to make a button to not postback to the server BUT allow it to append text to a textbox?

for example, when we click the bold tag when replying to a thread here on this forum, it instantly shows the appropriate tags - this is the behaviour I would like.

how is this possible to do in ASP.NET? (1.1)

In the codebehind, in the click event of your button you can assign the text to the textbox you wish.

just as normal?
so in C# code on the server, on the doubleclick event:

this.someTextBox.Text += "blah"

or do you mean on the client HTML side?

?

Using a JavaScript onClick for the button probably better. Then using JS you can set the text of your control. Sorry, I think the codebehind would require a postback if you wanted to do it all in the codebehind.

Yea, any server-side code requires a postback to run.

oooo lol ... JS

hm. so codebehind (client):

<script>
function DoAppendText()
{
   //find the textbox control??
   //once found, append the text?
}
</script>
..
..
<input type=button..........onClick = DoAppendText()>

or something like that? Sorry for the silly Q - its been a while!

Heh

<script type="text/javascript">
  function doAppendText(theText)
  {
    textbox = document.getElementById('mytextbox');
    textbox.innerHTML += theText;
  }
</script>

[...]

<textarea id="mytextbox" name="whatever"></textarea>
<input type="button" onclick="doAppendText('something'">

The other part is figuring out where the text to append comes from.

thanks! So I was kinda on the right lines :-P

the text to append will come from the button!

so we could have a "bold" button, then on the click of this button, it will append the text to the text box "<boldTag></boldTag>" or whatever

[RobDog888]

Dont forget the closing parenthesis.

I hate JS.

<input type="button" onclick="doAppendText('something')">

[penagate]

OK, so in my example it will be "something", as long as unlike me you remember to close the parentheses

For <boldTag></boldTag>:

<input type="button" onclick="doAppendText('&lt;boldTag&gt;&lt;/boldTag&gt;')">

awesome will give it a shot

thanks guys, we need people like you
