OnFocus/OnClick?

[Violet]

Your help would be greatly appreciated. Thank you in advance. Okay so I'm trying to do something along the lines of:

   .js
<script language="javascript" type="text/javascript"
function OnFocus(){
if (cost = 0) {
cost = ' ';
}
}
</script>
    .aspx
<cc1:Currency ID="Cost" runat="server" ShowCents="true" MaxLength="10"  onfocus="OnFocus()"/>
But Visual C# doesn't have an OnFocus function. How do I get around that?

Also, the variable (cost) is being defined in the code behind (.aspx.cs). How do I get Javascript to recognize it?

I don't know anything about ASP, but is there a way to force it to print a literal string out in the right place?

Alternatively, bind the onFocus from the JavaScript rather than in the HTML DOM.

Well, see, the problem is I'm not working in HTML at all (if I were working in HTML, I could easily do it). As for the printing out of a literal string in the right place - the problem is what is wanted is for when the user clicks into a textbox (defaulted to 00) and the default info that in the field they want to go away when you click into the textbox. So it's not really an open string they want, they want nothing in the field OnFocus if the value=0. Does that make since?

Yeah, that's well beyond my knowledge of ASP.

So you could maybe still bind the value via JS? Or is that not possible either? (I'm probably making a fool of myself for all you ASP folks )
