How to access a user control in a masterpage from a content page?

Lets say that I have a header user control in a master page, and want to change a property of the user control depending on what content page is loaded inside of the master page. How might I go about this?

Thanks!

You can use two methods. The first is by using Page.Master.FindControl('controlID'). Then you can cast it to the type of your user control. The second method is by adding a <%@ MasterType VirtualPath=""> OR <%@ MasterType TypeName=""%> tag to your aspx page. In the VirtualPath add the virtual path to the master page, or the class in the TypeName. You can then access everything with intellisense.

first find the user control in the masterpage as below.Then find the control you need to access their property.

UserControl uch = Page.Master.FindControl("ucHeader1") as UserControl;
PlaceHolder phProxylist= ucHeader1.FindControl("phProxy") as PlaceHolder;
DropDownList ddlproxylist1 = ucHeader1.FindControl("ddlProxyList") as DropDownList;
phProxylist.Visible = false;

Hope this helps.

Using a public property would work. In the content page's FormLoad method, you could do something like this (VB):

Dim myMaster as MyMasterPage = CType(Page.Master, MyMasterPage)
myMaster.MyUserControl.Text = "Hello!"

There's one other method, and that's by making a public property on the master page that exposes the user control.
