Controls calling other controls problem

Hi

I have a web page (content.aspx) that inherits from a master page
(MasterPage.master).

The master page has a control (which has to be on every web page, hence on
the master page) (MasterControl.ascx). When placed on the master page this
appears as <uc1:MasterControl ID="MasterControl1" runat="server" />.

The MasterControl's Page_Init() event will contain some code to examine the
Request object's properties (cookies) and calculate some value that it will
expose as a property. This property is called "ImportantProperty()".

Content.aspx has a specific control on it (ContentControl.ascx). When
placed on the web page this appears as
<uc1:ContentControl ID="ContentControl1" runat="server" />.

The problem...

The ContentControl.ascx's Page_Load() event must call the
"ImportantProperty()" in the MasterControl. The resulting value dictates
which view (another user control) to dynamically load at run time
(View1.ascx, View2.ascx or View3.ascx).

MSDN gives an example of how to call a property on the MasterControl from
the Content.aspx page but NOT from a control on the Content.aspx page.
Microsoft's example can be found on:
http://msdn2.microsoft.com/en-us/library/c8y19k6h.aspx I've tried to amend
their example without success....could someone put me out of my misery
please?

Many thanks

Have the page call to each control. Ultimately, the architecture is such
that both the user control and the web control are controls on the page. The
control of painting is passed to the master page, which makes it appear
different, but it is, in essence a user control.

Your other option is to iterate through the page controls until you find the
master page, use reflection and set the property. I have not personally
tried this, but this is the only way I know of getting the property.

Hi

Do you have any code example? I'm just not sure how the Content Page's User
Control can access properties on the Master Page's User Control....

Thanks
