change required textbox background color

Hey Friends,

I got the answer for this.

Add the following 2 functions in block on aspx page.

<pre lang="javascript">&lt;script language="javascript" type="text/javascript">

function DoBlur(fld)
{
fld.style.background="#FFFFFF";
}

function DoFocus(fld)
{
//fld.className = 'focusfld';
fld.style.background = "lightyellow";
}

&lt;/script></pre>

And on page apply these functions to textbox's or dropdownlist's OnFocus and OnBlur properties just like follows.

<pre lang="xml">&lt;asp:textbox id="txt1" runat="server" onfocus="DoFocus(this);" onblur="DoBlur(this);" /&gt;</pre>

Whenever you focus on that control it'll change the color of that control. Following code will focus the textbox when it is not validate.
<pre lang="vb">
Try
'Validation of textbox will go here
Catch ex As Exception
txt1.Focus()
Throw ex
End Try</pre>


Hope this code will help everyone who required this kind of functionality.

Thanks,
Yogesh
