You should return a model when you read the database.
A model is a strong typed class that you use to store data in.
Once you have the model populated, you can add 30 days to the date column by using .AddDays(30) in a loop.
So matter what month it is, it will calculate the proper date.
Eg Model:
public class Example {
public string Name { get; set; }
public DateTime Expires { get; set; }
}
Request data and populate the model
var examples = getExamples();
for each example in examples {
example.Expires.AddDays(30);
}
If your not using models, then you be able to figure this out somehow. You just need a DateTime Object and AddDays(30)
If it ain't broke don't fix it

Hi Friends,
Can anyone help me with this?
Using 3 tier architecture,how to fetch data directly from database table to textboxes when I clicked on select button in grid view,I have a table in SQL database.Upon clicking on select link button in grid view,the selected row values must be fetched from database table to text boxes and must be filled with respective values according to database table.I have used sqldatareader, taken OnSelectedIndexChanged ,written query in stored procedure for fetching selected row but values are not binding to text boxes.Any suggestions would be helpful.

As you did not showed what you have tried it will be hard us to know. Did you tried to debug and see if you really pulling any values back on your event to bind?

Couple of issues with your code in
FetchDetails method.
1. You have populated the result into arraylist object which is local to this function
2. You executing command object with ExecuteNonQuery, Reader and DataAdapter
3. You populated Dataset to return from FetchDetails in DAL and did not received it in calling method to bind data.
Populate your local variables in SelectChange event from DataSet object you reveiced from BAL and should work for you.

Here you go. You need to extract data from data table now in below code to populate your variables which you may be binding on screen.
DAL:
public DataTable FetchDetails()
{
con.Open();
DataTable dt = new DataTable();
using(SqlCommand cmd = new SqlCommand("spfetchdetail", con))
{
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@pid", pid);
SqlDataAdapter sda = new SqlDataAdapter(cmd);
sda.Fill(dt);
}
return dt.Table[0];
}
BAL:
public DataTable fetchdetail()
{
return dll.FetchDetails();
}
CS:
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
string pid = ""; string pname = ""; string pcid = ""; string sdesc = ""; string desc = ""; string qty = ""; string prce = ""; string len = "";
DataTable dt = bll.fetchdetail();
HiddenField1.Value = pid;
txt_proName.Text = pname;
ddl_category.SelectedValue = pcid;
txt_sdesc.Text = sdesc;
txt_ldesc.Text = desc;
txt_qnty.Text = qty;
txt_price.Text = prce;
txt_len.Text = len;
}

Thank u soo much for your reply.
But unfortunately i'm getting error in DAL
The name 'pid' does not exist in the current context
This is my Stored Procedure:
CREATE proc [dbo].[spfetchdetail]
<a href="https://www.codeproject.com/Members/pid">@pid</a> int
as
begin
select * from Products LEFT JOIN Category ON Products.P_C_id=Category.c_id where P_id=@pid
end

I might have removed all params so its error. You should pass the pid as parameter to DAL to resolve it.

In DAL
public DataTable FetchDetails(int pid)
{
con.Open();
DataTable dt = new DataTable();
using (SqlCommand cmd = new SqlCommand("spfetchdetail", con))
{
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@pid", pid);
SqlDataAdapter sda = new SqlDataAdapter(cmd);
sda.Fill(dt);
}
return dt;
}
In BAL:
public DataTable fetchdetail(int pid)
{
return dll.FetchDetails(pid);
}
In CS page,passing pid
string pid="";string pname = ""; string sdesc = ""; string desc = "";
string qty = ""; string prce = ""; string len = "";
DataTable dt = bll.fetchdetail(pid);
getting type conversion error

Hi,
I want when I enters information in the field, then the title of the field goes over the field.
Herre is my code:
@Html.TextBoxFor(model => model.FirstName, new { @placeholder = "FIRSTNAME", @class = "adresse-input"})
so in the field we have the text "FIRSTNAME", my purpose is when i enters information in this field, the text "FIRSTNAME" goes over the field.
And as long as the client has nothing to enter in a field, then the title remains in the field.
I search a lot if there is a trick to add in TextBoxFor to do that but i didn't find!
Thanks a lot

Have you looked into CSS for your class for placeholder? Below is something similar you are looking for -

Are you looking for something like this?

If not, then you'll need to explain what you mean by "goes over the field".

No. Because most people don't download random zip files.
If you want us to look at code (and I'm assuming you do) copy'n'paste it into your question, enclosed in pre tags:
<pre lang="cs">if ( x == y)
i = 6;</pre> Will give you:
if (x == y)
i = 6; You can add the tags via the "code" widget above the edit textbox.
And tell us where the error occurs, and copy the error message.
Just throwing a zip up on a dodgy download site and expecting us to download it, examine the content and work out where the problem might be is a bad idea ...

This is my learning project in which I wrapped Angular 7 in .Net Core. I'm in the process of preparing the project to run in a Docker Container and connect to MongoDB that runs in a Docker Container. So I had rewrite the project so it's knows if it's running in a Docker container or just running in IIS, and for development and production environments.
Accomplishments:
Figured out how to edit the Dockerfile, and inject 2 PFX files into the .Net Core container for portable SSL.
Figured out the port mapping on 5000, 5001, 44367, and how not to load Kestrel for development, yet load it for production.
I got my Docker-Compose dialed in to create MongoDB V4.08, the static data volume, bridge network to talk to the .Net Core container.
Created a a dual appSettings.json for production and development.
Got the user secrets going, but haven't figured out the Kestrel part yet.
So far so good. But I'm getting some crazy erratic results ...
It's like it's stuck in a build and won't update.
The project always displays data from a mongo database on on another server from previous builds.
I can't get the connection string to work with the user name and password under SHA-1 using the C# Mongo Drivers, but it works without credentials, I think that's my problem.
I go to debug to confirm that it detected the Docker Container, but I can't hit the break-point, yet project.dll symbols are loaded.
It's just gotten to the point where I'm going around in circles, and need to confirm some code before I change good code.
On the data, I can Roto3T into each Mongo and see the data I created which is all different.
In startup, I read the appSettings.development.json file and add 1 more option called IsContained, which is what I was trying to hit in the break-point. If I set this extra option here, I should be able to read it in my DBContext?
What I did was try and read the Environment Variable since I wasn't able to confirm the option. But would SETTINGS contain that option?
services.Configure<Settings>(Configuration.GetSection("Settings"));
services.Configure<Settings>(
options =>
{
options.MongoDB.Connection = Configuration.GetSection("MongoDB:Connection").Value;
options.MongoDB.Database = Configuration.GetSection("MongoDB:Database").Value;
options.MongoDB.Container = Configuration.GetSection("MongoDB.Container").Value;
options.MongoDB.IsContained = Configuration["DOTNET_RUNNING_IN_CONTAINER"] != null;
}
);
private readonly IMongoDatabase _database = null;
public DbContext(IOptions<<code>Settings</code>> appSettings)
{
bool.TryParse(Environment.GetEnvironmentVariable("DOTNET_RUNNING_IN_CONTAINER"), out var isDocker);
Console.Write("DBContext IsDocker = " + isDocker);
var client = new MongoClient(isDocker ? appSettings.Value.MongoDB.Container : appSettings.Value.MongoDB.Connection);
_database = client.GetDatabase(appSettings.Value.MongoDB.Database);
}
This is for a sanity check. I had to rewrite this to accommodate containers and my portable SSL certifcates. So if I use Kubernetes in the future, more .Net app containers can be spawned with SSL self contained. Online research says I need to use Kestrel for this and bind the port with the certificate. This crashed in development when trying to use the localhost certificate but now it works using the dev-certs certificate that is registered. Haven't tried it yet in Production using a real certificate, that comes when I fix the other issues first. But I will have more Kestrel questions soon. Any help or pointers on this would be appreciated.
public static void Main(string[] args)
{
var config = new ConfigurationBuilder()
.SetBasePath(Directory.GetCurrentDirectory())
.AddJsonFile("secrets.json", optional: true, reloadOnChange: true)
.AddJsonFile($"appSettings.{Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT")}.json", optional: false, reloadOnChange: true)
.AddJsonFile($"certificate.{Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT")}.json", optional: false, reloadOnChange: true)
.Build();
<pre>
var appSettings = config.GetSection("Settings").Get<Settings>();
var dbSecrets = config.GetSection("Database").Get<DbSecrets>();
var env = Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT");
bool.TryParse(Environment.GetEnvironmentVariable("DOTNET_RUNNING_IN_CONTAINER"), out var isDocker);
var host = CreateWebHostBuilder(args).Build();
if (env == "Production" && isDocker)
{
var certificateSettings = config.GetSection("certificateSettings");
var certificateFileName = certificateSettings.GetValue<string>("filename");
var certificatePassword = certificateSettings.GetValue<string>("password");
var certificate = new X509Certificate2(certificateFileName, certificatePassword);
var builder = new WebHostBuilder()
.UseKestrel(
options =>
{
options.AddServerHeader = false;
options.Listen(IPAddress.Loopback, 44367, listenOptions =>
{
listenOptions.UseHttps(certificate);
});
}
)
.UseConfiguration(config)
.UseContentRoot(Directory.GetCurrentDirectory())
.UseStartup<startup>()
.Build();
builder.Run();
}
host.Run();
}
Note:
Visual Studio does an OK job in getting your project into Docker for testing, but left out so many factors.
And the Internet is jammed pack with outdated information on the topic.
All the Angular stuff seem to work fine, and I think it's all .Net Core related.

Well I figured out a few things today.
My crazy issues came from the Angular wrapped in .Net Core project image that I started with.
There's a file called app.constants in Angular and a class called Configuration that is used to set the url to services in Angular to call .Net Core API's, and all the calls where going to my production server. Thus the wrong data. I just changed that file and now I can hit the breakpoints. Now I'm calling API services in the Dockerized container; I think I can fix it now that I can walk the code. It's a start in the right direction now.
If it ain't broke don't fix it
