Hi, there -
I'm creating some classes that inherit different controls. I'm doing this since there are still some design decisions to be made in regards to colors, etc, and I believe if I have a custom controls in place, I can simply change the property once on the custom control and those changes would propegate throughout the app when instances of those custom controls are used.
For example, I have a class that inherits the UltraTextEditor control by using:
Inherits Infragistics.Win.UltraWinEditors.UltraTextEditor
This has worked fine for me until I needed to do this with UltraMaskedEditor. It does not appear to allow inheritance. Can anyone else confirm this, and if this is the case, is there a reason?
I'm expecting to be able to use the statement:
Inherits Infragistics.Win.UltraWinMaskedEdit.UltraMaskedEdit
Thanks for your time!
I'm using Visual Basic (in Visual Studio 2005)
This is literally all of my code from the class I'm trying to create:
Public Class MaskedEditNBS Inherits Infragistics.Win.UltraWinMaskedEdit.UltraMaskedEdit End Class
End Class
The error I get is:
"Type 'Infragistics.Win.UltraWinMaskedEdit.UltraMaskedEdit' is not defined."
I have confirmed that my project has the appropriate references.
The reference used is: Infragistics2.Win.UltraWinMaskedEdit.v7.3 , version is: 7.3.20073.38, runtime is: v2.0.50727
You should also have a reference to the Infragistics2.Win.dll and Infragistics2.Shared.dll.
Thanks for the quick reply! I appreciate it.
I do have references to both of those .dlls and the same error persists. I should also mention that I'm using a trial version (that does not expire for another 10 days of usage). Would this have any impact?
Otherwise, would the fact that I'm using Visual Basic be a problem? I have not yet attempted this with C# yet, but I can give it a go if that would help diagnose this.

I doubt the language would have any effect, although I did use C# to test it out before, worked fine for me. Nor do I think the trial version would have anything in it to short it out, the other dlls worked fine according to you, so singling out MaskedEdit would seem a little odd.
I had one of our Developer Support Engineers try out the issue in VB.Net and he was able to get the class to subclass. So it does not seem language specific.
I guess what you could try would be to start a test windows form application, drag a masked edit control onto the form which will load the references. Ensure that all three are there, if any are missing I would guess that the installer didn't put them into the GAC (not likely but possible). After that delete the MaskedEdit from the form and add a class file to the winforms solution that you subclass the masked edit with and see if that works.
If that fails, then you would have a project to submit to developer support so that they could debug it.
I created a new test application per your suggestion and it worked perfectly. I then went back into my original project, removed all Infragistics references, and then added them back in again, and I no longer get the error.
It appears something with my project/solution file was not quite right, but re-adding the references did the trick.
Thanks again for the quick and helpful replies. I appreciate it!
