Accessing values of one customer Control from another custom control

[Suresh Kumar]

Hi All,
I am a newbie in creating ASP.NET custom controls. I have created one custom
control say X.ascx for getting the location of the user like Country, State,
and City. And I have created another control Y.ASCX which has X.ascx control
also. The problem is how do I access the controls on X.ascx fromY.ascx
control.

Can anyone guide me on this???

Thanks for the help.
Suresh

You don't.

ASP.NET is object oriented. Among other things this means that you shouldn't
have Y.ascx (which is a User Control, not a Custom Control) poking around in
the guts of X.ascx. What happens if X.ascx decides to change what controls
it uses?

Instead, you should create public properties in X.ascx which return the
values which other controls (including Y.ascx) might be interested in. For
instance:

X.ascx:

....
<asp:TextBox runat="server" id="txtCountry" />
....
X.ascx.cs:
public string Country
{
get {return txtCountry.Text;}
set {txtCountry.Text = value;}
}

Y.ascx:
....
<uc1:X runat="server" id="X1"></uc1:X>
....
Y.ascx.cs:
....
// you can now access X1.Country

Hi John,
Thanks for the reply. I have created the public properties in X.ascx control
but how do I access it in Y.ascx?
Can you please paste some example here?
