How to reference an object in a user control from its parent page

[moondaddy]

I have a page which has a user control called CheckOutStatusBar and it lives
in a table call like this:

<%@ Register TagPrefix="uc1" TagName="CheckoutStatusBar"
Src="Navigation/CheckoutStatusBar.ascx" %>
html.....
<td>
<uc1:checkoutstatusbar id="CheckoutStatusBar1"
runat="server"></uc1:checkoutstatusbar>
</td>



I need to change the formating of a link button in CheckoutStatusBar.ascx
from its parent page. How an I get a reference to it from the parent page?

Thanks.

All you do is put a declaration into the page:

Protected WithEvents CheckoutStatusBar1
As "ProjectName"."UserControlClassName"

and then it becomes available to you in code.

hope this helps

Hi,

CheckoutStatusBar oCheckoutStatusBar1 =
FindControl("CheckoutStatusBar1");

but you need to expose public or internal function from your user
control that will handle link formating change.

It's best if you treat user controls like class instances (which they are).
This means that a user control shouldn't be exposing its link buttons to
the outside world. Instead, the user control should expose a method or
property which allows the link button formatting to change. For instance, in
the user control:

private bool _linkUnderlined = true;
public bool LinkUnderlined
{
get {return _linkUnderlined;}
set
{
_linkUnderlined = value;
if (_linkUnderlined)
{
lnkLinkButton.Styles["text-decoration"] = "underlined";
}
else
{
lnkLinkButton.Styles["text-decoration"] = "none";
}
}
}
