Hey,
A bit backstory: I am working for some time on my Text-Templating engine project Morestachio and all the time i compare the performance of Morestachio against other engines like cottle, handlebars.net, scribain etc and with the latest release of .Net5 i was thrilled as microsoft promised another out-of-the-box performance improvement like the one we saw when net.core came out where each version was measurably faster then the previous one. I read some block posts like this one: Performance Improvements in .NET 5 | .NET Blog but when i did my usual performance comparisons I discovered more or less the opposite.
I have two performance metrics: Historical performance tests including only Morestachio using Nunit and a project using the BenchmarkDotNet lib.
BenchmarkDotNet:
.net472:
| Method | Mean | Error | StdDev | Gen 0 | Gen 1 | Gen 2 | Allocated |
|------- |---------:|----------:|----------:|---------:|--------:|------:|----------:|
| Bench | 2.019 ms | 0.0041 ms | 0.0036 ms | 257.8125 | 15.6250 | - | 1.57 MB |
.NET5:
| Method | Mean | Error | StdDev | Gen 0 | Gen 1 | Gen 2 | Allocated |
|------- |---------:|----------:|----------:|--------:|-------:|------:|----------:|
| Bench | 2.219 ms | 0.0044 ms | 0.0039 ms | 85.9375 | 3.9063 | - | 705.5 KB |
.NetCore 3.1:
| Method | Mean | Error | StdDev | Gen 0 | Gen 1 | Gen 2 | Allocated |
|------- |---------:|----------:|----------:|--------:|-------:|------:|----------:|
| Bench | 1.427 ms | 0.0035 ms | 0.0033 ms | 95.7031 | 5.8594 | - | 783.67 KB |
this also performance difference is also present in the other test (i will not bother to post here).
Yes Net5 is way more efficient in memory consumption but in comparison slower then even pre NetCore.

If I put bigger or smaller wheels on a car, it will affect it's speed; all other things being equal.
Memory and response time is like that. And we have different cars.

For an article I wanted to create a VB.Net demo project with Master/Detail GridView and RichTextColumn.
Parts of my demo project are taken from CP articles about Master/Detail GridViews.
But most of them have the issue with the keys not working on the childView - that prevents moving through the child grid with arrow keys.
Same happens with keys page up/down and pos1/end.
Example: DataGridViewExtension[^]
Instead of navigating through the childView those keys let you navigate through the Main/Parent Form.
There is only one without that issue - but in C# and I do not understand how the issue is fixed there:
Master Detail Datagridview in C#[^]
That's why I tried to do the childView with my own subForm, but that was no good idea.
Today I could migrate that C# project (without the issue) to vb and got it working - without the keys issue.
But still cannot see the reason for the keys issue and why all works in the Master Detail Datagridview in C#.
Any ideas what causes the keys issue and how to fix it?

The "parent key" is used to filter children in the "child view"; that's it.
Every time the selected parent changes, a new set of children is retrieved or filtered using the parent key.
That's the pattern. How people choose to abuse it, is another matter.

I probably do not understand what mean - why should an 'Id'-Key which filters the datasource of the childView control have any effect on the function of the 'Keyboard'-Keys for the childView control?

It doesn't. Where did I mention "key board"?
If your problem is that your "app" is not behaving as "expected", it's because you've either hooked up something wrong, or didn't when you should, or defeated it's default behavior.
I was telling you what "should" happen. You implement parent-child relations; they don't just "happen".
(And VB had "navigation controls" that c# never had).

It is exactly the same concept. The important thing is what information you put in the log.
|
|
|
|
|
i'll try more different ways but not working for me , i want audit to record every things in my system where user performed !

We have no idea what you are doing, or what you mean by "not working for me". If you want help with a programming problem then you need to provide proper details.

I think he's missing the part where one actually "calls" the logger.

I think he's missing much more than that.

Such a concise and detailed question (it' not working for me) deserves a a detailed response - then fix it.
Are you trying to audit database changes, keystrokes on the web site, movement through your web site. What are you trying to achieve, if you give us some detail we may be able to help you.

Then please get on and do it. You asked this question a month ago, what have you done since then?
|

You have a choice, depending on your database you can add triggers spit to audit activity or you can add some sort of auditing to your DAL in c# that records each activity into the database.
Personally I create triggers spit in the database to audit all master file tables IE I do not audit transaction tables.

Keypress and keydown event occurs when click on flexgrid control but value is not showing.when use doubleclick event is working that.
|
|
|
|

FlexGrid? Why on earth would you be using such an ancient control?
Your question doesn't make sense. What value? Why are you using the KeyPress and KeyDown events? For what? What is the DoubleClick event being used? For what? What are you expecting to work that doesn't?

Hello All,
This is my first application in asp.net core
Table Like this ->
PublisherMater : PublisherId,PublisherName,TotalBooks
PublisherDetails: BookName,ReleaseDate,AuthorName
My question is : I want to manage master and details entry using asp.net core mvc with code first approch.
first step : Create Model
secound : Create MVC Controller with view using Entity Framework
anybody have any example like this ?
Thanks in advance

Your tables are bad. You should not be putting "TotalBooks" in the PublisherMaster table at all.
What you should be doing is something closer to this:
public class Publisher
{
public int PublisherId { get; set; }
public string PublisherName { get; set; }
public ICollection<Book> PublishedBooks { get; set; }
}
public class Book
{
public int BookId { get; set; }
public string BookTitle { get; set; }
public string AuthorName { get; set; }
public Date? ReleaseDate { get; set; }
}
Every publisher can publish any number of books, hence the collection in the class.
