I don't see the need for a gridview there but regardlesss, for the TextBox to populate when the ComboBox selection changes you will need to write code for the ComboBox's SelectedIndexChanged[^] event.
Follow the example in that page, see what it does, and then see if that's what you want to do, if it is come back here and tell us, if its not, come back and ask further questions, showing what you've done

There are many reasons for differences in speed on different systems; it is not a valid comparison.
Use the best guess

The person who makes the comparison is working in a famous non profit server organization and sound like he knows what he is doing.

Then maybe you should go and talk to him. This sort of question is not really appropriate for these forums.

This is an objective question if we comparing these with the same hardware. Latest Java+linux, latest windows+c# are two objective objectives that can be tested and compared with measurable speeds of specific tests.

That may be, but this is still the wrong forum for this type of discussion; try the Lounge[^].

people from lounge saying they don't talk about this kind of serious programming topic over there, they prefer to talk something else like drinking. Check out the replies over there of one of my posts.

How can this has nothing to do with programming when we are discussing which is faster? Speed is extremely important for a programming language, if not c++ would not even exist.

Because you have not asked a programming question. You are talking about some benchmark results that are posted on another website, so go to that website and discuss it with the people who can help you. If you have a proper programming question then this is the place for it.

This is a forum of C# in general, not just "C# syntax".
My question is a specific question directly related to C# with possible objective answer.

Seeing as we are aruging the toss, it isn't. The code may be written in c#, but this is compiles into an intermediate language, CIL. The comparison really compares the speed of CIL execution against Java's JIT compiled (I assume) code. A more accurate description would be a comparison of the performance of the frameworks. You could have tested using VB.net in place of c# and the results would more than likely have been near identical, because it too compiles to CIL.
This really isn't a programming question, you are asking about the speed comparison of two frameworks. The code is a black-box from this point of view and its only relevancy is whether it is a fair and representative test.

You describe well but this is still a question strongly related to c#. As I said before, this forum should be topics about C# but not only C# syntax.

Sorry but it isn't. Your question is about the relative speeds of different languages on different systems, and there is no definitive answer. Some combinations of systems are sometimes faster than others; that is all that can be said with certainty.

variable E is the hardware, which is a constant
A is C#, B is latest windows like windows 7 64bits ultimate. Combine to run a script in constant E to have a speed number
C is Java, D is a popular linux Ubunut 64 bits. Combine to run a 99.9% similar script in constant E to have a speed number
These two results can be calculated, and the result must have 99.9% confidence level to believe even the script would have 0.1% different.
A and C are programming languages and both are directly in formula, so discuss in either java or C# forum perfectly make sense.
If the graph is based on same machine, and very likely it is, the conclusion is Java+linux is faster than c#+windows, but it is hard to directly compare Java and C# since those have very different speed in different OS.
This is the conclusion already, my question is WHY and HOW.

We have ALL explained, and you just don't seem able to understand a simple point. The issue has nothing to do with Java or .NET. It's down to the operating system. I'm really not sure how many different ways we can tell you this before you get the point. You seem to fixate on one thing and aren't prepared to listen to answers that contradict that point. The conclusion here is that a program running on Linux outperforms a program running on Windows.
The only way to do a comparison would be to test a program that directly compiles down to an executable on both platforms, and see how they compare. And no - your question has nothing to do with C# - that's only one small part in this equation.

then why c# is much slower than java in linux? The link has this result too. As i just said, it is os+language, not just one of these.

You aren't comparing like for like. That's the problem, and I can't see how you don't get that. Java running on Linux runs faster because there's less overhead on Linux. How can you not understand this? If you are that obsessed with speed, write it in C or Assembly.
|
|
|
|
|
then why c# in linux is also slower than java in linux? Less overhead in linux cannot be a reason for this case.

C# on Linux is not an official product. It has nothing to do with Microsoft - it's implemented through something called Mono. There is no .NET for Linux.

C# is a only windows language? You think so?
|
|
|
|
|
What are you talking about?
C# runs within the .NET framework on Windows and under the MONO framework in Linux. If you don't understand that basic fact then you will never understand what people are trying to explain to you.
