What I'm doing wrong with this implementation? - c#

I'm trying to Implement ExportToPDF() action method in my MCV.CORE web app.
Now obviously in my EmployeeCategory class I have different data types(int,string,double).
So, my conclusion why I'm getting error, is because data type needs to be only string type. Which is not possible in my case.
I'm not sure how to correctly implement this action method.
Errors that I'm getting is:
Cannot convert type Test_Project_Web.Models.EmployeeCategory to string[]
No best type found for implicitly-typed array
My simplified code:
EmployeeCategory.cs :
public class EmployeeCategory
{
[Key]
public int Id { get; set; }
[Required]
public string? Name { get; set; }
[Required]
public string? LastName { get; set; }
[Required]
public string? Address { get; set; }
[Required]
public double NetSalary { get; set; }
[Required]
public double GrossSalary { get; set; }
}
EmployeeCategoryController.cs :
private ApplicationDbContext Context { get; }
public EmployeeCategoryController(ApplicationDbContext _context)
{
Context = _context;
}
public IActionResult Index()
{
return View(this.Context.EmployeeCategories.Take(6).ToList());
}
[HttpPost]
public FileResult ExportToPDF()
{
List<EmployeeCategory> employees = (from employee in Context.EmployeeCategories.Take(6)
select new[] {
employee.Id,
employee.Name,
employee.LastName,
employee.Address,
employee.NetSalary,
employee.GrossSalary
}).ToList<EmployeeCategory>();
//Building an HTML string.
StringBuilder sb = new StringBuilder();
//Table start.

//Building the Header row.
sb.Append("<tr>");
sb.Append("<th style='background-color: #B8DBFD;border: 1px solid #ccc'>Id</th>");

//Building the Data rows.
for (int i = 0; i < employees.Count; i++)
{
string[] employee = (string[])employees[i];
sb.Append("<tr>");
for (int j = 0; j < employee.Length; j++)
{
//Append data.
sb.Append("<td style='border: 1px solid #ccc'>");
sb.Append(employee[j]);
sb.Append("</td>");
}
sb.Append("</tr>");
}
//Table end.
sb.Append("</table>");
using (MemoryStream stream = new MemoryStream(Encoding.ASCII.GetBytes(sb.ToString())))
{
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
PdfWriter writer = new PdfWriter(byteArrayOutputStream);
PdfDocument pdfDocument = new PdfDocument(writer);
pdfDocument.SetDefaultPageSize(PageSize.A4);

pdfDocument.Close();

}
}


I don't think this error has anything to do with the data types of your Employee properties and has more to do with you trying to cast an Employee to a string[]:
string[] employee = (string[])employees[i];
Aside from this not being possible (using the method above) I don't think it is necessary as you can obtain the properties and their values to output them as it appears you're attempting to do in your question.
employees.ForEach(employee =>
{
sb.Append("<tr>");
foreach (var propertyInfo in employee.GetType().GetProperties())
{
sb.Append("<td style='border: 1px solid #ccc'>");
sb.Append(propertyInfo.GetValue(employee));
sb.Append("</td>");
}
sb.Append("</tr>");
});

Display total price for each row where quantity comes from database and price is entered by user

I have a table in my Blazor Asp.Net 5 application with 4 columns:
Title
Quantity
Price
Total
Each time a user enters a price in column 3, I want the column 4 cell to be updated live by 3x2 (quantity X price) for the row in which he types it. How can I achieve this?
There may be many rows and data arrives from database.
Data is displayed to user and allows him to enter prices for each product row, meanwhile quantity is already populated:
#for (var i = 0; i < advert.Products.Count; i++)
{
var index = i;
var item = advert.Products[i];
<tr>
<th scope="row">#index</th>
<td>#item.Title</td>
<td>#item.Qty</td>
<td><input /></td>
<td>Sum here</td>
</tr>
}
#code {
[Parameter] public int AdvertId { get; set; }
public Advert advert;
protected override async Task OnInitializedAsync()
{
advert = await adRepo.GetAdvert(AdvertId);
}
}

Here is a working demo like below:
Model:
public class Advert
{
public int Id { get; set; }
public string Name { get; set; }
public List<Product> Products { get; set; }
}
public class Product
{
public string Title { get; set; }
public int Qty { get; set; }
public int Price { get; set; }
}
Index.razor:
#for (var i = 0; i < advert.Products.Count; i++)
{
var index = i;
var item = advert.Products[i];
<tr>
<th scope="row">#index</th>
<td>#item.Title</td>
<td>#item.Qty</td>
<td><input #bind="#item.Price" /></td>
<td>#{
var total = item.Price * item.Qty;
}
#total</td>
</tr>
}
#code {
[Parameter] public int AdvertId { get; set; }
public Advert advert;
protected override async Task OnInitializedAsync()
{
advert = await adRepo.GetAdvert(AdvertId);
}
}

looping through dictionary inside dictionary in jquery

I'm trying to set values to table containing textboxes in each cell. For instance a table having a first column containing names, and rest of the columns containing textboxes to add marks of the given assignment for individual students. For that I used dictionary to hold given marks by the instructor and when the page is load, the marks are set to the relevant textboxes. however my iteration over Dictionary in jquery doesn't seem to be really working. I'm missing somewhere in loop. Below is my code.

Edited:-
Since I've managed to pass the results in the required textboxes. I'm here surrounded by another issue which is the next assignment submission. The first column contains the submitted marks already, and this time instructor would carry out the marking of the next assignment. Therefore, The system would look for the next column as the previous column already contains marks.
$("#saveResult").click(function () {
$("#tbl tr.item").each(function () {
$(this).find("input.txtbox").attr("disabled", "disabled");
var Mkrs = $(this).find("input.txtbox").val();
var Id = $(this).find("#stdassgnid").val();
alert(Mkrs)
$.ajax({

How to add checkboxes to each day in this calendar view?

I am trying to add a simple checkbox feature to each day in my calendar view. It must be inline with the style of the current calendar and when a bool is selected it must be able to save the changes to the database. Any suggestions would be appreciated.
My main issue at the moment is the checkboxes that are being selected are not being saved to the db.

UPDATE
By adding this line of code to Calendar.cshtl:
#if (calArg.Date.Day == calArg.Date.Day)
{
#Html.CheckBoxFor(m => m.CompletionRequested, new { #checked = calArg.CompletionRequested });
}
It surprisingly works, so i guess i'd like to know how to alter the css style sheet in calendar index to have the checkboxes flush with the calendar design (i.e. inline with the calendar and not just above it) and how to save changes to the bool to the db.

Have this inside the foreach loop:
#Html.CheckBoxFor(m => m.CompletionRequested , new { #checked = evt.CompletionRequested });
UPDATE:
Answer to your question in comments. Do HttpPost to controller and pass model data.
[HttpPost]
public ActionResult CalendarIndex(CalendarArg model)
{
// Check that model is valid
if(ModelState.IsValid)
{
// CODE here to update Database
return RedirectToAction("Index"); // or where ever you want to go
}
else
{
return View(model); // Return back to View, model is not valid
}
}
UPDATE 2:
If you want to add a class name you can do it like this:
#Html.CheckBoxFor(m => m.CompletionRequested , new { #checked = evt.CompletionRequested, #class = "checkbox" });
Or you can add css like this:
input[type="radio"]:checked
{
// css when radio button is selected
}
input[type="radio"]
{
// css when radio button is not selected
}
These CSS styles is global so every input element with type radio will get styles.
And when you want to change changes to db context, you need first find the current one from context. Then add true value to CompletionRequested property and then call SaveChanged method from your context. You'r first question was to get checkboxes on your calendarView, not how to save changes to db. That's another question.

C# MVC - Convert String to Variable

How can I convert a string to be used as a variable? I have a List of strings that I want to be able to loop through and call data from my Model.
My code:
Controller:
List<string> reportContentsCharts = new List<string>();
//Pseudo Code
//If chart is selected added it to reportContents. So in the view instead of calling #Model.getChart1 from the view I can reference this reportContents.
//For Example:If chart1 and chart2 are selected
reportContentsCharts.Add("getChart1");
reportContentsCharts.Add("getChart2");
IndexViewModel viewModel = new IndexViewModel()
{
chart1 = makeChart1(DictionaryofData), //Returns an image and sends to IndexViewModel
chart2 = makeChart2(DictionaryofData),
chart3 = makeChart2(DictionaryofData),
chart4 = makeChart2(DictionaryofData),
chart5 = makeChart2(DictionaryofData),
chart6 = makeChart2(DictionaryofData),
reportContentsCharts = reportContentsCharts
}
private byte[] makeChart1(Dictionary<string, Double> DictionaryofData)
{
//code to construct chart and return as an image.
}
IndexViewModel:
public Byte[] chart1 { get; set; }
public Byte[] chart2 { get; set; }
public Byte[] chart3 { get; set; }
public Byte[] chart4 { get; set; }
public Byte[] chart5 { get; set; }
public Byte[] chart6 { get; set; }
//This code is repeated for all 6 charts
public string getChart1
{
get
{
string mimeType = "image/png";
string base64 = Convert.ToBase64String(chart1);
return string.Format("data: {0}; base64, {1}", mimeType, base64);
}
}
View:
<table>
for(int z = 0; z< Model.reportContentsCharts.Count / 2 ;z++) //At most 2 charts can be selected
{
<tr>
<td ="center">
<img src=#Model.reportContentsCharts[z]/>
</td>
<td ="center">
<img src=#Model.reportContentsCharts[z+1] />
</td>
</tr>
}
</table>
Under lying issue:
Currently when I run this code it returns me a broken image. I am thinking this might be a syntax issue? I have a handful of graphs that can be displayed on my webpage. Based on input from the user only a select few of the graphs will be displayed. The first thing I did was hard coded a position in the html for each graph and then use if() statements to determine whether to display the graph. The problem with this is that, based on the user input, the selected graphs can appear on separate lines. This creates bad alignment and spacing issues.
I understand that this might not be the best way to do this, but I felt like that it was the simplest solution.
Thanks for any suggestions or help.

It looks to me like the root of the problem is your poorly designed ViewModel. You need to normalize it:
private Dictionary<string, byte[]> Charts = new Dictionary<string, byte[]>();
public string GetChart(string name)
{
get
{
string mimeType = "image/png";
string base64 = Convert.ToBase64String(Charts[name]);
return string.Format("data: {0}; base64, {1}", mimeType, base64);
}
}
public string AddChart(string name, byte[] data)
{
Charts[name] = data;
}
Then you can write your controller something like this:
IndexViewModel viewModel = new IndexViewModel()
{
reportContentsCharts = reportContentsCharts
}
for (int i = 0; i < 6; i++)
{
viewModel.AddChart("chart" + i, makeChart("chart" + i, DictionaryOfData));
}
And finally, you can write your view like this:
<table>
for (int z = 0; z < Model.reportContentsCharts.Count; z += 2)
{
<tr>
for (int c = z; c < z + 2; c++)
{
<td align="center">
if (c < Model.reportContentsCharts.Count)
{
<img src="#Model.GetChart(Model.reportContentsCharts[c])"/>
}
</td>
}
</tr>
}
</table>
