Problem Accessing Page Controls in a page that has a master page.
I have a problem with accessing the controls of a page that has a masterpage. I am trying to access the Page.Controls from the code behind in the class file but no controls are returned.I can access single controls (ex. txtAddress.Text) but not the whole array of controls (ex. Page.Controls).
The controls structure is.. MasterPage > PlaceHolder > MyPage.aspx

I have a master page (say site.master) with a status Label in it.
I have a content page ( say content.aspx) that has a user control (say usercontrol.ascx).
One of the Button Click Events in the usercontrol.ascx needs to pass on some text onto the status label on the masterpage(LabelStatusMsg) and display it.
I have been able to do this directly off a content page (content.aspx) by using the following code (VB) on the master page

How would I structure my site in this scenario: I'd like to use a dropdownlist all over my site, sometimes in a regular page, sometimes in a master page, and sometimes in a user control.

However, I notice a lot of code duplication because I have to declare the control in everywhere, in my base page (which all my pages inherit from), in my base master page (which all my master pages inherit from) and in my base user control (which all my user controls inherit from).How should I be...i have 3 pages student information , i filled two pages ,then go to 3rd page .

This being said, I advise you to consider another approach.Your master page should not use code that depends on the design of a particular content page. Your content pages should depend on your master page, not the other ...Accessing Master page control from child page
In my application I have implemented a customized error control, which gets visible on any error raised.
Issue is, in one of the page where we have implemnted Update Panel, and onClick of a button I wants to raise a error on the control in Master page.
The Page object has a Master property that will reference the properties of the master page. Note that you will need to apply the MasterType directive to your page or use the Page.MasterPageFile property to reference the master page properties.Christopher Reed"The oxen are slow, but the earth is patient."
