This is not the problem with C# application, check your service you are using for auto-complete that might taking lot of time or you are doing some operation on key down.

Very, very vague question, not really useful.

There is no particular reason - you need to look at your code (which is probably in a .asmx file) and check that.
Without your code, we cannot really help you any further!

We still can't tell from that - it's a bit like you phoning the garage and saying "my car is broken - fix it" and hanging up. Without telling them where you are, what the car is, and what happens to cause the problem, they would have to guess. Or more likely, not do anything because they don't know where to find you.

Solution 2

There only one particular reason: the clumsy hands of the application developer. As to .NET and C# themselves, they are very stable and support development of very stable application which are very easy to maintain at least if proper development practices are utilized.

i got it, but you know the problem is not in the development environment.ie the application works well in my system. the problem is in the clients system when installed.

Solution 3

First thing that comes to mind is a threading issue. If the autocomplete takes a long time to execute and is executing on the UI thread, it will interrupt any other UI operations, thereby "freezing" the application until it is done. Perhaps you can, as OriginalGriff suggested, post your code for us to look at.

This does not discount the possibility of a threading issue. If your system is more powerful than the client's system, then the code that gets executed on the UI thread might happen so fast that you don't notice the delay; but on the client's system it takes just long enough that it is noticeable from time to time.

When the application freezes, how long does it freeze before continuing? Does the client force quit it while it freezes? Is there any other patterns that you can see as to when it freezes and when it works perfectly?

Solution 4

I think your MinimumPrefixLength = "1", increase it by 3 , I am agree with "OriginalGriff" we cannot really help you Without your code

Solution 5

Agree with others. You didn't provide enough details in your question.

And my guesses are,
1) May be memory issue
2) Infinite loop
3) etc.,
