Access global resources in an asp.net control
Text='<%$ Resources:Resource, WizardStep1Resource1 %>'
Text is the name of the property you want to set. Resource is the name of the global Resourcefile resp. ResourceClass and WizardStep1Resource1 is the name of the Resource Text.

You can only access a resource in App_GlobalResources explicitly, using the implicit wiring i.e. meta:resourcekey="WizardStep1Resource1"
is applicable only for local resources

To access a resource in App_GlobalResources, use explicit localization like
<%= (string)GetGlobalResourceObject("ResourcesClass", "WizardStep1Resource1") %>
