Question

I have defined a user control, ExpressionControl, under the namespace:

TriggerEditor.UserControls

I have a form, “IfEditor”, under the namespace:

TriggerEditor.Forms

When I add an instance of my control to the form (naming it expCondition), the following code is generated in the Designer to create the control:

this.expCondition = new TriggerEditor.UserControls.ExpressionControl();

This results in the following compilation error:

The type name 'UserControls' does not exist in the type 'TriggerEditor.Forms.TriggerEditor'

I don’t understand why it is looking in “TriggerEditor.Forms.TriggerEditor”; that’s not what the code says. Now, I can resolve this error manually by modifying the line, removing the “TriggerEditor.” that preceeds “TriggerControls”, as such:

this.expCondition = new UserControls.ExpressionControl();

This satisfies the compiler, however I obviously don’t want to do this every time I add an instance of my ExpressionControl to a form. How do I avoid this situation?

Answer 1

It looks like you might have a TriggerEditor class within the TriggerEditor.Forms namespace; is this the case?

If so, because the TriggerEditor class is within your current namespace, you are “closer” to this class, and therefore it is looking for a subclass.
