Question

I have a UserControl with some predefined controls (groupbox,button,datagridview) on it, these controls are marked as protected and the components variable is also marked as

Answer 1

Change property to defined [private] to [protected] defined at xx.designer.cs which is originally machine generated code.

for example

    private System.Windows.Forms.Button btnSave;

to

    protected System.Windows.Forms.Button btnSave;

and rebuild it.

then you can change the property of inherited control.
