You should add the following directive to content page:

<%@ MasterType VirtualPath="path to master page" %>

Add public property ih master page code-behind file:

public DropDownList DropDownList
{
    get { return dropDownList; }
}

Add event handler in content page:

Master.DropDownList.SelectedIndexChanged += OnSelectedIndexChanged;

Assign Master.DropDownList.SelectedValue to Label.Text in event hanlder.
