Make sure you add a reference to your user control in your page aspx:
<%@ Reference Control="~/UserControls/Controlname.ascx"%>

shakti5385 Make your control public in the master page, something like:
public MycontrolInMaster
{
get
{
return this.MyControlName;
}
}
Then in the content page, using this.Page.Master and casting it for the MasterPage type, you'll be able to use your control.

stealth_pt Im not sure if you fixed this but I have a similar issue:
USING CODE BESIDE! My Master page has an attribute classname="MyMasterClass". In the master page I have a user control with an attribute classname="MyUserControlClass" defined in the .ascx file.
In the master page file I then define a public property to the user control:
public MyUserControlClass MyControl { get{return myControlIdOnThePage;} }In the page that inherits the master page in the "Page_Load" I do:
MyMasterClass mmc = new MyMasterClass(); mmc.MyControl.Visible = false;This produces the error "Object reference not set to an instance of an object"....The intelliense recognizes the public control property so I know its there....any ideas?

migo I actually made this more better by doing
<%@ mastertype virtualpath="~/pathtomasterpages/mymasterpage.Master" %>Then in the Page
Master.MyUserControl.Visible = false;

migo The problem in your code is that your control is not inicialized. So in your content page what you should do instead is something like this:
MyMasterPageType theMaster = (MyMasterPageType)this.Page.Master;
theMaster.MyControl.Visible = false;
And then it will work!!! :)

shakti5385 Proabably the problem is that you have the ASPX in one project and the control in other. Just make the reference to that project in the ASPX one.
Hope it helps
