I have a MVC application and want to generate PDF using HTML. In here I use wkHTMLtoPdf exe to do my job.
I call to an action method from client side using jquery. Then it hit to below method.
public FileContentResult ExportInvoiceASPDF(string invno)
{
try
{
Byte[] bytes;
var fullUrl = this.Url.Action("pdfCustomerInvoice", "Report", new { invNo = invno }, Request.Url.Scheme);
bytes = WKHtmlToPdf(fullUrl);
FileContentResult result = new FileContentResult(bytes, "application/pdf")
{
FileDownloadName = "PriceNotification"
};
return File(result.FileContents, "application/pdf");
}
catch (Exception ex)
{
throw;
}
}
In here I called to WKHtmlToPdf function for getting byte stream. (Below code extracted from stackoverflow thread)
public byte[] WKHtmlToPdf(string url_input)
{
try
{
var fileName = " - ";
var wkhtmlDir = ConfigurationSettings.AppSettings["wkhtmlDir"];//Directory of wkHtmltopdf exe
var wkhtml = ConfigurationSettings.AppSettings["wkhtml"];//wkhtmltopdf exe location
var p = new Process();
url = url_input;
p.StartInfo.CreateNoWindow = true;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.RedirectStandardError = true;
p.StartInfo.RedirectStandardInput = true;
p.StartInfo.UseShellExecute = false;
p.StartInfo.FileName = wkhtml;
p.StartInfo.WorkingDirectory = wkhtmlDir;
string switches = "";
switches += "--print-media-type ";
switches += "--margin-top 10mm --margin-bottom 10mm --margin-right 10mm --margin-left 10mm ";
switches += "--page-size Letter ";
p.StartInfo.Arguments = switches + " " + url + " " + fileName;
p.Start();
//read output
byte[] buffer = new byte[32768];
byte[] file;
using (var ms = new MemoryStream())
{
while (true)
{
int read = p.StandardOutput.BaseStream.Read(buffer, 0, buffer.Length);
if (read <= 0)
{
break;
}
ms.Write(buffer, 0, read);
}
file = ms.ToArray();
}
// wait or exit
p.WaitForExit(60000);
// read the exit code, close process
int returnCode = p.ExitCode;
p.Close();
return returnCode == 0 ? file : null;
}
catch (Exception ex)
{
// set your exceptions here
return null;
}
}
Here I execute the view. (the page which I want to export as PDF)
public ActionResult pdfCustomerInvoice(string invNo)
{
var inv = _customerInvoiceService.GetCustomerInvoice(invNo);
InvoiceSummaryReportsVM invRepVM = new InvoiceSummaryReportsVM();
//My data assigning part going here
return View(invRepVM);
}
Here is pdfCustomerInvoice html.

The issue is when I execute the code, it is generated the PDF without styling. (All data align to left side.)
But when I call to "pdfCustomerInvoice" method directly, the html comes properly with styling.
In here I have styling issue. Please give me a direction for fixing this problem.
It seems that bootstrap won't load then.
Try to link bootstrap css from your file system.

I have an edit form page on my website that allows users to edit quantities, on this page I used editorFor's which look like this
#Html.EditorFor(model => model.item_qty, new { htmlAttributes = new { min = 0, #class = "form-control" } })
And I have a submit button that looks like this
<input type="submit" value="Save" class="btn" />
I want to make it so that if the user increases the qty, it will go ahead and run the post method. But on the other hand, if a user was to decrease the qty, I would want the save button to look like this
<input type="submit" value="Save" onclick="confirm()" class="btn" />
Where it gets the user to confirm before running the post.
How can I make my save button change based on what the user types into the editorFor?
Here is my entire view page as requested

For the on change you can on your editor for:
#Html.EditorFor(model => model.item_qty, new { htmlAttributes = new { onchange = "OnChangeEvent(this)", min = 0, #class = "form-control", #id ="someId" } })
<script type="text/javascript">
function OnChangeEvent(){
var itemQty = $('#someID').val(); //This will give you value of editor for
alert("new value is: " + itemQty);
//Call some controller function here and do your increase/decrease logic and return value so we know what to do. also perform your save in controller too if needed.
#Model.IsChanged = true;
//do other functions here also like change button
//if decrease add below
btn.Attributes.Add("onclick", "confirm()");
//if increase remove and perform save.
}
</script>
You can also change the button from that method. There is no good way to do on call events at a server level, unless using blazor, so javascript is your best bet here.

I'm new to MVC. Using the scaffolding mechanism I have managed to create CRUD operations on the database table. This works well with working on a single MVC Model at a time (Mapped to a single Model). I want to implement add & edit of a List into database (will be empty list initially), the user should be able to add as many number of items as he need and then submit the data to the database. I want this list to be of dynamic length, so that when user edits the data he should be able to add few more new elements into the Model also deleting few individual Model. I couldn't find proper resource to come up with a solution. Little help will be much Appreciated.
Scenario - Person can have multiple Addresses or Person will not be having any addresses. How to add multiple Address by adding addresses into the view and how to perform edit on those? If one of the Address needs to be deleted then how to do so?
Thank you.

I'm using Web API for the backend process. I have added a delete and Add New Row button in the view for Address tab. For now it is working with just a single Model, I wanted to know how to implement it for a Dynamic list, So as to A Person can have 'n' number of Addresses and he can edit whichever he want and also delete based on AddressId. I know the code seems quite low rated. Just want to know the syntax and semantics on how to proceed with working on List. Sorry for Messing up things. Thank you.
Got a solution from Matt lunn.
Follow this link :-
https://www.mattlunn.me.uk/blog/2014/08/how-to-dynamically-via-ajax-add-new-items-to-a-bound-list-model-in-asp-mvc-net/
It is implemented by using custom HtmlHelper Extension and creating Html.EditorForMany().
Thanks a lot for the trick Matt Lunn. Works Exactly How I wanted. :)
I'm following this guide here to create a step wizard to traverse multiple pages with forms on each while saving each forms data to store in my db but the problem I'm having is on the second page 'addressDetails'. When I press the prevBtn to return to the previous page 'basicDetails', my form is trying to do client side validation and I get all the validation errors instead of posting to my action method to see whether the prevBtn or nextBtn was pressed
Here is my addressDetails page

Here is my action method
[HttpPost]
public ActionResult AddressDetails(UserAddressViewModel addressViewModel, string prevBtn, string nextBtn)
{
YogaProfileBankAccount obj = GetBankAccount();
if (prevBtn != null)
{
UserBillingViewModel billingViewModel = new UserBillingViewModel();
//bd.CustomerID = obj.CustomerID;
//bd.CompanyName = obj.CompanyName;
return View("BasicDetails", billingViewModel);
}
if (nextBtn != null)
{
if (ModelState.IsValid)
{
//obj.Address = data.Address;
//obj.City = data.City;
//obj.Country = data.Country;
//obj.PostalCode = data.PostalCode;
return View("AccountDetails");
}
}
return View();
}
So here is what happens when I press previous, all the fields try to get validated
I am a new developer and I am trying to populate a drop down list as the result of what was chosen in a previous drop down list. I am stuck and would appreciate a full answer, I think I need a script somewhere but am not sure where to put it, and where to include the script tag.
Controller:

I am making my MVC application. My view PickGroupForHomework is redirected to by
return RedirectToAction("PickGroupForHomework", "Account", new { subject_id = id, qty=model.qty });
Of course subject_id and qty are parameters of PickGroupForHomeworkViewModel. The controller looks like this:
public ActionResult PickGroupForHomework(PickGroupForHomeworkViewModel model)
{
ClassDeclarationsDBEntities2 entities = new ClassDeclarationsDBEntities2();
model.groups = entities.Groups.ToList();
model.users = entities.Users.ToList();
int id = model.subject_id;
var subj = entities.Subjects
.Where(b => b.class_id == model.subject_id)
.FirstOrDefault();
if (subj != null)
{
model.subject_name = subj.name;
}
if (ModelState.IsValid)
{
DateTime myDate = DateTime.ParseExact(model.deadline+ " "+model.time, "yyyy-MM-dd HH:mm",
System.Globalization.CultureInfo.InvariantCulture);
ClassDeclarationsDBEntities2 entities2 = new ClassDeclarationsDBEntities2();
int total = entities2.Tasks.Count();
for (int i=0;i<model.task_names.Count;i++)
{
ClassDeclarationsDBEntities2 entities3 = new ClassDeclarationsDBEntities2();
int maxid;
if (total == 0)
{
maxid = 0;
}
else {
maxid = entities3.Tasks.Max(u => u.task_id);
}
var task = new Models.Task(model.task_names[i], model.subject_id, myDate, model.points[i], maxid + 1);
entities3.Tasks.Add(task);
entities3.SaveChangesAsync();
}
return RedirectToAction("OperationSuccess", "Account");
}
else
{
return View(model);
}
return View(model);
}
At first, everything loads correctly with correct URL including data passed from previous view. The form I am displaying now includes validation. If a user makes mistake in form, which indicades ModelState.IsValid=false, the window is reloaded. But I do not know why it is reloaded without data passed from previous window: subject_id and qty. What am I doing wrong?

Your problem is subject_id is not in your form, so when you post back the form it sends 0 value to the server.
you need to add a field inside form , you can add a Text or hidden field
#Html.HiddenFor(m => m.subject_id)
