Hello group, a question please. The data from my databases all come out in a single string per row in the .csv file, how can I print it in a cell per field in the .csv file? I attach images and code for more clarity with the problem. Thanks
<pre lang="C#"> public partial class CS : System.Web.UI.Page {
protected void ExportCSV(object sender, EventArgs e)
{
string constr = ConfigurationManager.ConnectionStrings["PRUEBASConnectionString"].ConnectionString;
using (SqlConnection con = new SqlConnection(constr))
{
using (SqlCommand cmd = new SqlCommand("SELECT * FROM Customers"))
{
using (SqlDataAdapter sda = new SqlDataAdapter())
{
cmd.Connection = con;
sda.SelectCommand = cmd;
using (DataTable dt = new DataTable())
{
sda.Fill(dt);
//Build the CSV file data as a Comma separated string.
string csv = string.Empty;
foreach (DataColumn column in dt.Columns)
{
//Add the Header row for CSV file.
csv += column.ColumnName + ',';
}
//Add new line.
csv += "\r\n";
foreach (DataRow row in dt.Rows)
{
foreach (DataColumn column in dt.Columns)
{
//Add the Data rows.
csv += row[column.ColumnName].ToString().Replace(",", ";") + ',';
}
//Add new line.
csv += "\r\n";
}
//Download the CSV file.
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition", "attachment;filename=SqlExport.csv");
Response.Charset = "";
Response.ContentType = "application/text";
Response.Output.Write(csv);
Response.Flush();
Response.End();
}
}
}
}
} }

We have embedded different visuals from a PBIX file onto a asp.net core razor view.
We have achieved that when a user clicks on a row in a table visual, detect the item and corssfilter the other embedded visuals as the user clicks.
On the Power BI environment you can do the same, but by pressing the CTRL key, you can select multiple rows and then it will filter the whole visuals on that page.
As we achieved the crossfiltering selecting just one we thought it would do the same by pressing CTRL, the problem is that PowerBI Embedded visual is not detecting the CTRL key and it is not actually detecting that we are selecting more than one row and it changes the whole filters to the first selected row.

Hello,
I am looking for an approach sanitize all string coming from the browser to my application where I won't have to modify all action methods on all controllers.
Maybe add a filter on the controller itself?
Welcoming suggestions.
Thank you!!

That seems like a bad idea to me. You shouldn't be storing "sanitised" values; you should be storing the raw values, and encoding them properly when you output them. The encoding will vary depending on where you're outputting them, so storing a single "sanitised" version of the value wouldn't help.

Yes, I want to encode when I am outputting but wondering whether there is a way where I change once and it applies everywhere.
I had the OnActionExecuted filter in mind but feel like there could be a better way.

Apologies if you've seen this before in the Net Core section ( deleted now ), I decided here is a better fit
How can I freeze the column header row of a table so that its always visible ?
Despite googling for hours I can't find a way to do this, I wan't the table header to be frozen ( as you can do in Excel ) any ideas guys ?

Add position:sticky;top:0; to the cells in the table header:
.table-frozen thead th,
.table-frozen thead td {
position: sticky;
top: 0;
background: white;
} (The background colour is required to prevent the body cells from bleeding through when the table is scrolled.)
Unfortunately, you can't apply it to the <thead> or <tr>:

Tried that Richard but no joy, there is a navbar above the table that maybe has some bearing on things
Edit
I commented out the navbar and your solution works - I have the navbar always visible and fixed to the top so it must be interfering

How is it fixed to the top, and does it have a fixed height?

That makes it tricky - the fixed top navbar appears on top of the sticky table header, and doesn't have a fixed height. I suspect you'll need some Javascript to fix that:
.table-frozen thead th,
.table-frozen thead td {
position: sticky;
top: var(--content-top, 0);
background: white;
}
body {
padding-top: var(--content-top, 0);
}
const updateNavbarHeight = function(){
const navbar = document.querySelector(".fixed-top");
const top = navbar.offsetHeight;
document.documentElement.style.setProperty("--content-top", `${top}px`);
};
document.addEventListener("DOMContentLoaded", function(){
updateNavbarHeight();
const ro = new ResizeObserver(() => updateNavbarHeight());
ro.observe(document.documentElement);
}); Demo[^]

You'll need to add the JS and CSS, and then add the table-frozen class to your table.

Hasn't made any difference Richard

Works fine in the demo I posted:
Edit fiddle - JSFiddle - Code Playground[^]
Check that you included the JS and CSS correctly, and that the page isn't loading a cached version of your CSS or JS files. Also check the developer console for errors.

Based on that vague, rambling, and unclear description? No, nobody can help you.
You need to provide a clear and precise description of what you are trying to do, what you have tried, and where you are stuck. Include sample input and expected output, the relevant parts of your code, and the full details of any errors.

What might help is for you to ask a question here using specific terms deployed in your ASP.NET code scheme. If you don't have a scheme, find one here using the search engine, crossing your fingers just before you hit the "do-the-search" button.
To get started, find terms here (for example):Two way data binding in ASP.NET[^]
Like I said "might" ... as I use that overbearing display of the word "may" here as an epexegesis.

I write in Postman this URL for Get method: https://localhost:7033/api/restaurant and I get 404 not found result. I don't know where is the problem. For https://localhostlocalhost:7033 it works, so it must be something wrong with [Route("api/restaurant")]
Here is the Controller code:
[Route("api/restaurant")]
public class RestaurantController : ControllerBase
{
private readonly RestaurantDbContext _dbContext;
public RestaurantController(RestaurantDbContext dbContext)
{
_dbContext = dbContext;
}
[HttpGet]
public ActionResult<ienumerable<restaurant>> GetAll()
{
var restaurants = _dbContext.Restaurants.ToList();
return Ok(restaurants);
}
}
and launchSettings file code:
}
{
"iisSettings": {
"windowsAuthentication": false,
"anonymousAuthentication": true,
"iisExpress": {
"applicationUrl": "http://localhost:8196",
"sslPort": 44311
}
},
"profiles": {
"RestaurantApp": {
"commandName": "Project",
"dotnetRunMessages": true,
"launchBrowser": true,
"applicationUrl": "https://localhost:7033;http://localhost:5033",
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
}
},
"IIS Express": {
"commandName": "IISExpress",
"launchBrowser": true,
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
}
}
}
}
