I have a form with 3 user controls in it. On the left side(of the form) i have place holder for displaying the picture, bottom part of the form will have control showing status messages/errors/warnings.In the remaining part that is in the center of the form I have a tab control showing different pages(Each page has got user controls embedded on it).As per the tab page selected my picture holder should display the corresponding picture and also the corresponding messages/errors/warnings should be displayed in the status bar control.Which design pattern will be suitable for achieving this scenario?

That's not what Design Patterns do.

Who told you that programming is done by using design patterns?

I wish I could vote this Yoda-sentence a +5 !

p.s. Is it a testimony to our times, or my age, that I instinctively wrote "Yoda" rather than "oracular" :) ?

Sergey Alexandrovich Kryukov 19-Oct-14 12:34pm

I quoted Yoda several times, but not here. Here I did not even though about it. That was my own saying.
What in Yoda would be relevant here?

"What in Yoda would be relevant here?" Antinominal rhetoric, however, in this case, neither anastrophic, or hyperbatonic.

Sergey Alexandrovich Kryukov 19-Oct-14 14:13pm

If fail to see antinomial rhetoric here, either. I was just hoping your would help me to find out exact Yoda quotation, which I would happy to use, in this or other cases.
Thank you.

By "antinominal" (note: not "antinomial") I was referring to a concept in the work of Michael Harmon (Princeton) where antinominal is used to describe a "good paradox." ref. : http://books.google.com/books?id=P_gjwnNgtHwC&pg=PA279&lpg=PA279&dq=%22good+paradox%22+harmon&source=bl&ots=HKPPgmiEao&sig=Vw8631d_VYV2h4RiVlUM-_mIxng&hl=en&sa=X&ei=OQNEVM6EIeTVmAXqy4HoCw&ved=0CBwQ6AEwAA#v=onepage&q=%22good%20paradox%22%20harmon&f=false

Very obscure that may be, and, for that to you, I apologize.

Sergey Alexandrovich Kryukov 19-Oct-14 15:03pm

Ah, I really confused antinominal with antinomial, so I have to apologize, not you... We already had the "antinominal" discussion before, where I discussed the "there is no verbal knowledge", where the concept of "verb" (general "word", in this case) could be consider as a minor generalization of "nom" in "antinominal".

However, this case is even more general; it's rather something about some illusion of knowledge. One hero of J. D. Salinger's "The Catcher in the Rye" thought that the ability to write compositions is the skill to put some letters/words in place. Likewise, some think that programming is putting design patterns here and there...

I don't know why, but this makes me think of the Wizard of Oz's "solutions" for the unique problems of the Scarecrow, the Tinman, and the Cowardly Lion :) If only we could solve beginner's dilemmas by sending them on a magical quest that would convince them they already have what they need !

It's only great that real life is more complicated... :-)

Yoda could say:
"So use design pattern you want?
Then learn programming you must!"
:)

BillWoodruff 19-Oct-14 16:08pm

I like that ! I think "learn programming you must" could well be a "motto" for CP QA, perhaps along with the long-version of that:

"search/read/study/experiment/observe/analyze to learn programming you must."

George Jonsson 19-Oct-14 21:04pm

Very true.

Sergey Alexandrovich Kryukov 19-Oct-14 21:42pm

This is very nice.

However, I imagined something more harsh saying, like "Design patterns have strong impression on the weak-minded".

Indeed, it reminds me how people learn and perceive mathematics. Middle school students and those who stop learning mathematics on early stages, perceived it as something about the formulas. When people start specializing in mathematics, the whole idea to use formulas nearly completely goes out of consideration, giving room to much more serious (and more interesting) things.

Likewise, starting with certain level of programming, students have to realize that the patterns describe something, by definition, more or less trivial and well-known. No creative work can consist of shuffling trivial and well-known things. If a developer stalls at such level, this is the same as staying at the level of middle school in mathematics.

Is your Application working okay now ?

When you say "a part of my Form changes" I expect you to be talking about some change in the size/location of something on the Form, or the Form itself, but you seem, in the rest of your question, to only be talking about the contents (Image displayed, messages in TextBoxes) changing. Can you clarify this ?

I wonder if you are asking how you could implement this UI in such a way that your Application design is somewhat Model-View-Controller in structure (MVC).

As have been said in the comments, there is no real design pattern for what you want to do. As you seem to have a pretty good idea about what you want to do it is just a matter of getting started.
However, you might want use one or more design patterns in the code behind depending on how you get data into your application or if you want to save error information to a log.
Here are some different design pattern definitions http://en.wikipedia.org/wiki/Software_design_pattern[^]
