Hi,
I use the flowing code in my usercontrolDesignerClass to remove some properties:
it works fun and user cann't access the "BackColor" property in desgin view at property grid. but also user can access it bye coding such as :
myUserControl.BackColor =// A color

how can i remove the properties in both design view and code view
thanks

To put it simply, you can't.

Hmm. Why would you want to do this??? If you are devloping controls that you are intending to sell (or give away for that matter) you should NOT restrict a potential client or developer from changing how the control looks. For example, if your control is bright neon pink and yellow and I have a more contemporary website or application that I want to plug your control into but you restrict me from altering its appearance, why am I going to buy it?

I agree with dparsons, the whole reason the BackColor property is part of the base control class is because EVERY control should have complete flexibility over how it looks by its client code. This is not just because people may like to change it (and they should be able to if they want to), but also an Accessibility issue, some people may be color blind, need high contrast to read clearly etc.

However, you could override it and mark it as obsolete, I think that would throw compiler warnings at you though, since the base BackColor is not obsolete, but would enable you to now allow client code to call it. Not sure, never tried it!

ooohh
the property "BackColor" is just a sample. my question is about all properties. and be sure if i remove the backColor property(that i do this action never), i will add the new property with feature greater than the BackColor..
but my question is abou any property.. i don't want realy remove the BackColor property..
i just want to now how can i remove some property of control from code view and design view...
regards

Of course you can...

Simply decorate your properties with attributes like EditorBrowsableAttribute and BrowsableAttribute to hide them from the Grid and IntelliSense:

http://msdn2.microsoft.com/en-us/lib...attribute.aspx
http://msdn2.microsoft.com/en-us/lib...attribute.aspx

Combine that with an ObsoleteAttribute to discourage the use of the property, and it's unlikely people will find / use it. Additionally, you can override the property and have it throw a NotImplementedException.

Cheers,
