Hi all,
I'm using user controls for my site and want to know if its possible to
set the values of properties of of the user controls through the main
.aspx page. For example. I have a label in the user control. I made a
public property for the user control but can't seem to figure out how to
set the value of the property from the main .aspx page. Any help would
be great.

Here's how you could do it, assuming your user control was setup to
have a TagPrevix of bleh and a TagName of blah:
<bleh:blah runat="server" id="myUserControl"
PropertyName="PropertyValue" />
or you could do it like:
<bleh:blah runat="server" id="myUserControl" />
<script runat="server" language="VB">
Sub Page_Load(sender as Object, e as EventArgs)
myUserControl.PropertyName = PropertyValue 'where PropertyValue is
of the right type
End Sub
</script>

Thanks Scott. How about if you have this setup. I have a main .aspx
page and on that page I have two user controls. Can one of the user
controls get/set properties on the other user control and vice versa
from within the user control?

Why do you want to do this? Think of a User control as a black-box.
You should be able to use them on any page, and the user control
shouldn't care what other user controls are or aren't present. If you
try to get user controls to affect other user control's properties you
are violating this model.

I see your point. I've made adjustments already and have my pages
working, I was just wondering if it were possible.
I'm building a forms-based authentication app that has the main .aspx
page with a header user control and I also made the form into a user
control. I was trying to get the form user control to set certain
properties for the header user control based on if the user successfully
logged in or not. I just realized though, that I shouldn't make the
login form a user control. I should make it into a custom server control
instead. Then, from within my header user control, I could get the
value of a property in the login server control. In my header user
control, I'd like to set a label to display "Login" if they are not
logged in or "Logout" if they are logged in. I'd also like to get the
user's first name to display it in another label in the header user
control. (hope this makes sense).
I think creating a custom server control for the login control makes
more sense. What do you think?

hello all,
Im trying to do the same thing. I have a logon user control with 2
properties.
One for password and one for username.
Should I be using a custom server control instead.
In actual fact, I don't know the difference.
Can someone explain.
thanks
RuSs
