VS 2015 Designer Error - The type 'foo' has no property named 'bar'


  • I am using a SignatureBoxWrapper control on my WinForm. It has a property 'AllowDigitalSig'. The code compiles and runs fine, but the designer complains The type 'OpenDental.UI.SignatureBoxWrapper' has no property named 'AllowDigitalSig' and so I can't display the WinForm to make changes. But the property is defined. Comments on MSDN Help seem to indicate this is due to a bug in VS. Any suggestions?

  • "designer complains" means you have build error?

    Do you have a machine running VS 2013? Do the same thing there do you have the same issue.

  • Thanks for the reply. No build errors. It compiles and runs fine on VS 2015

    By 'designer complains' I mean I cannot view the form in the designer to modify it. I see a warning 'To prevent possible data loss before loading the designer, the following errors must be resolved:

    The type 'OpenDental.UI.SignatureBoxWrapper' has no property named 'AllowDigitalSig' 

    Same result in VS 2013

    On SignatureBoxWrapper I can change

            [Category("Property"), Description("Set true if, in this context, you wish to allow providers to digitally sign."), DefaultValue(false)]
            public bool AllowDigitalSig {
    			set {
    				butESign.Visible=true && PrefC.GetBool(PrefName.SignatureAllowDigital);
    public bool AllowDigitalSig = true

    And the problem goes away

    Thank you
