I want to display different messages from a database in rows of divs, it's for a portion of the site where people will be able to share stories. I want it to look like rows of post-it notes with the stories on them, then if they want to read more they can click on one and it goes to a detailed view of it. It's an ASP.net application, so I've been using VB for a lot of the other stuff.
It's a pretty simple database, with two-three fields (PK, Story, name) and I think it will use a page load event. Just not sure how to access the data. Previously I dealt with displaying grids and rows, but now I want something more organic.
I'm not an ASP guy, but the question seems a little vague. When pulling the data, you'll want to truncate the info from the database for the front page and then link to a full page with all of the info from that post.
For the display, you could use the help of the jQuery masonry plugin.

I was trying to make an Instagram-like app with Flutter. I which users can promote their for some amount, and once the promotion is done I'll add the post id into the promoted posts database.
Now, I want to focus on natural posts (I mean posts of user's 'following list') so I used a StreamBuilder to listen to the friends' collection.
Meanwhile, I also wanted to mix the content with promoted posts. Seriously, can't find a solution.
Any idea about implementing this? This will be a great help for me.
The promoted posts' collection would be of a large space, so I'm kinda worried about retrieving all documents in the collection at once and showing it up.
Let me know your thoughts :)
I am not clear of your question but still what I can say is,
If you want to mix both of the posts, then just add data from both stream builders to a list. Its like list.addAll(data)
Another thing is, you are worried about large data load. You can load/fetch data on scroll. You can find tutorials by searching lazy loading, infinite scrolling etc.
Let me know if you got it!

How would one find out if it's even possible on specific site?
For example https://forums.eveonline.com/default.aspx?g=topics&f=257
There are many more sites where I wanted to display more results per page but option is not available.
Without knowledge of the code base, there is no way to know whether you can change the page behavior via a URL parameter, other than trial and error.
If the site is well designed, all URL parameters ought to be validated against a white list, so it should not be possible to hack the URL. So you should not rely on this.
I know that this is not answering the real question and i know that John Wu is right: You can't obtain this via querystring if you don't know if this is coded server side. What i think is that there is always a way:
For example, in this case you can use rss feed (the button placed at the bottom of the page):

My Asp template
I'm creating my first ASP.NET website for selling furniture and I am confused about creating my database. I want to sell products for many categories like bedrooms, and every user can add products to cart; here is my master page template
I introduce you a simple database design for the issue using 4 proposed tables in the following:
Persons; to keep your users info in it.
ProductCategories; to keep the product groups in it as mentioned like bedroom.
Products; to keep the all products with their categories.
Carts; actually this is not mandatory, you can manage this by cookies.
Note: This proposal is very very basic and simple, so it can be extended by your needs.
Here is the mentioned tables with their fields(in the minimum) as graphical interface in the Microsoft SQL Server design:

Is it possible to scrape data automatically from websites that require a validation code each time a webpage is accessed? Such as the case when the website shows you a picture of the code and asks you to enter what is shown in the picture. I'm using the rvest package. Is this possible to do?
What you're trying to do is beat CAPTCHAs. That's possible but very hard. This is a spammer's hardest job - to come up with an algorithm smart enough to fill out those fields correctly. It's not something you're supposed to do, the whole point of those validation codes is to prevent access from non-humans. If you're smart and motivated enough to figure out how to answer those questions programatically, you can probably make more money doing that than whatever you're trying to do :)
Some websites offer a direct API, which is the way you're supposed to interact with their data. But getting past a CAPTCHA by scraping is not an easy deed.

I am using masterpages in my aspnet website. .
Whenever I refresh or reload or redirect to another page of same application , the complete page is getting reloaded which taking lot of time in binding header and footers. ....
Is there any other way keep header and footer constant and only content inside it get reloaded........
That is not something MasterPages is going to solve for you.
MasterPages are intended to easily reuse the framework of your site.
Picture from MSDN explaining the behavior of MasterPages:
As you see, it's just A+B.
If you want to prevent reloading it every time, use AJAX.
