Ok,
Is their an easy way to get textboxes in webforms to change backcolor
when receiving focus? Any help or links are appreciated.
Thanks,
Trint
 
Trint,

You would have to use javascript to do this. There should be an event
for obtaining focus (onenter, I believe). In there, you would set the style
for the textbox so that the background color (backcolor on style, I believe)
is the color you want.

Here is a little sample script:

<html>
<body>
<input type="text"
onfocus="javascript:this.style.background='#090909';"
onblur="javascript:this.style.background='#FFFFFF';">

<input type="button">
</body>
</html>


Hope this helps.
 
Where would I put that in my code? (this code:)

public static void setFocus(Page page, string controlID)
{

string javascript = string.Format( @"<script language=""javascript"">

var called = false;

if(document.body.onfocus)
orig_document_body_onfocus = document.body.onfocus;

document.body.onfocus = document_body_onfocus;

function setFocus()
{{
var control = document.getElementById(""{0}"");
if(control)
control.focus();
}}


function orig_document_body_onfocus(){{}}

function document_body_onfocus ()
{{
if( !called )
{{
called = true;
setFocus();
}}

orig_document_body_onfocus();
}}



if( window.__smartNav && window.__smartNav.restoreFocus)
{{
orig_window__smartNav_restoreFocus = window.__smartNav.restoreFocus;
window.__smartNav.restoreFocus = window__smartNav_restoreFocus;
}}

function orig_window__smartNav_restoreFocus(){{}}

function window__smartNav_restoreFocus()
{{
setFocus();
orig_window__smartNav_restoreFocus
}}


</script>", controlID);

page.RegisterStartupScript("focus", javascript);

}// end setFocus

public static void setFocus(WebControl control)
{
setFocus(control.Page, control.ID);

}// end setFocus

public static void setFocus(HtmlControl control)
{
setFocus(control.Page, control.ID);

}// end setFocus

thanks

Trint,

You aren't going to put that in your C# code, it's going to be
javascript that is run on the client side. You don't want to do this kind
of thing on the server side, since it would require a postback, just to
change the background color on a textbox.
 
trint,

Why not just place it on the ASPX page, and not in your C# code? It's
javascript to be run on the ^client^ side. You don't place this in your C#
code.
 
I tried that like this and got nothing.

trint,

I would remove the </script> element from after the input element.
