How to import csv file and display the data on html table then save on sql database in asp .net core

I'm struggling with importing csv file in my project.
I want to upload a csv file and display the data before saving to sql database.
I'm using asp .net core razor pages.
Here is my C# method for Importing:
public ActionResult OnPostImport()
{
IFormFile file = Request.Form.Files[0];
string folderName = "Upload";
string webRootPath = _hostingEnvironment.WebRootPath;
string newPath = Path.Combine(webRootPath, folderName);
StringBuilder sb = new StringBuilder();
if (!Directory.Exists(newPath))
Directory.CreateDirectory(newPath);
if (file.Length > 0)
{
string sFileExtension = Path.GetExtension(file.FileName).ToLower();
ISheet sheet;
string fullPath = Path.Combine(newPath, file.FileName);
using (var stream = new FileStream(fullPath, FileMode.Create))
{
file.CopyTo(stream);
stream.Position = 0;
if (sFileExtension == ".xls")//This will read the Excel 97-2000 formats
{
HSSFWorkbook hssfwb = new HSSFWorkbook(stream);
sheet = hssfwb.GetSheetAt(0);
}
else //This will read 2007 Excel format
{
XSSFWorkbook hssfwb = new XSSFWorkbook(stream);
sheet = hssfwb.GetSheetAt(0);
}
IRow headerRow = sheet.GetRow(0);
int cellCount = headerRow.LastCellNum;
// Start creating the html which would be displayed in tabular format on the screen
sb.Append("<table class='table'><tr>");
for (int j = 0; j < cellCount; j++)
{
NPOI.SS.UserModel.ICell cell = headerRow.GetCell(j);
if (cell == null || string.IsNullOrWhiteSpace(cell.ToString())) continue;
sb.Append("<th>" + cell.ToString() + "</th>");
}
sb.Append("</tr>");
sb.AppendLine("<tr>");
for (int i = (sheet.FirstRowNum + 1); i <= sheet.LastRowNum; i++)
{
IRow row = sheet.GetRow(i);
if (row == null) continue;
if (row.Cells.All(d => d.CellType == CellType.Blank)) continue;
for (int j = row.FirstCellNum; j < cellCount; j++)
{
if (row.GetCell(j) != null)
sb.Append("<td>" + row.GetCell(j).ToString() + "</td>");
}
sb.AppendLine("</tr>");
}
sb.Append("</table>");
}
}
return this.Content(sb.ToString());
}
Here is my frontend code:
<h2>Import</h2>
<br />
<form method="post" enctype="multipart/form-data">
<div class="row">
<div class="col-md-4">
<input type="file" id="fUpload" name="files" class="form-control" />

</script>
they ajax call doesnt reach the c# method. Please help I'm not sure what is it I'm missing out on this code above.And also pleaae advise how i can get to save the data to sql after importing the csv file.

1.You can try to change public ActionResult OnPostImport() to public ActionResult OnPostImportFromExcel().Becasue your ajax url is /Home/ImportCSVFile?handler=ImportFromExcel.
2.Or you can change ajax url to /Home/ImportCSVFile?handler=Import.

And about saving data to db,you can refer to this.

I want to print to pdf file in javascript, where outputstream and pdfwriter

I am trying to create a PDF from a server-side controller (report) (ireport) with ajax (and so on), and try to return the data to pdfwriter, servletoutputstream, and httpservletresponse. (I do not know exactly what I'm doing, but I'm doing it this way).
The original purpose was to send a server-side pdf file to the client, find the printer and print without a preview window.
Among them, I wrote 'application / pdf' on the server side and 'datetype: text' on the client side ajax (there is an error if I do not use ajax datatype: text)
If you print the results to the console, they will only be listed as unknown code.
Currently I am trying to put it into an iframe frame.
Question!
1. What should I do to use the text string sent to server -> client as pdf or script code?
(I have already asked you two weeks ago)
2. How do I send a pdf to server -> client? I would like to apply it to the screen by expressing it directly in code instead of downloading it. To print out.

Not able to load the Gridview on Load

I am not able to load the gridview on page load. It keeps giving me
Uncaught TypeError: Cannot read property 'length' of undefined.
I have mnetioned the code and the handler beneath. Please help me solve the issue. The issue happens in the Jquery.
<script type="text/javascript">
$(document).ready(function () {
BindGridView();
});
function BindGridView() {
$.ajax({
type: "POST",
url: "../Pm/uc/G.ashx/GetMailDetail",

Cannot read property 'length' of undefined.
This error is coming because you are accessing the data.d without checking data and accessing data.d.length without checking data.d
Do something like this:
if(data){
if(data.d){
if (data.d.length > 0) {
$("#grdDemo").append("<tr><th>Username</th></tr>");
for (var i = 0; i < data.d.length; i++) {
$("#grdDemo").append("<tr><td>" +
data.d[i].Username + "</td> <td>");
}
}
}
}

A console application to get a web page resource, using c# (javascript may cause this)

Aim: To download a website source with using a console application. You can find the used class in the program below.
Question: I use the code below to download a data (source) of a web page. Imagine you use chrome; If you enter first this query string, the web page itself redirects you a view HTML page and you see the data.
Entering this URL, to show the results it redirects itself to second page below. I make it by using javascript.
www.xyz.com/aaa.html?search=aaa&id=1
it redirects here: www.xyz.com/ViewResult.html
In an explorer, It works fine . I see 4 HTML tables inside the page when I use google chrome view source option. Bu in my application I see only two tables of the 4 . The two tables inside the web page is missing.(the missing two tables are the second and third.)
How can I overcome to this problem? I want to get the source of the page as I see in chrome.
Bonus informations: There is no iframe.
The particular Code :

Trying to sort repeater rows with this jQuery

I am trying to sort repeater rows with this jquery . But I am not able to save sort items. Please help me . how can save sorting in database as well as in .aspx page?Thank you in advance
<script language="javascript" type="text/javascript">
$("#defaultList").sortable();
$(document).ready(function () {
$("#defaultList").sortable(
{
update: function (ev, ui) {

var originalIdAndSequenceNumber = '';
var index = 0;
for (i = 0; i <= items.length - 1; i++) {
if (items[i].length == 0)
continue;
var item = $('#' + items[i])[0];
originalIdAndSequenceNumber += item.attributes["originalId"].nodeValue + ":" + index.toString();
originalIdAndSequenceNumber += "|";
index = index + 1;
}

}

$.ajax(
{
type: "POST",
dataType: "text",
url: "AjaxService.asmx/UpdateSequenceNumber",
data: "s=" + originalIdAndSequenceNumber,
success: function (response) {
}
}
);
}
my ajax method:
[WebMethod]

string updateQuery = #"update dnn_Table_1 set SortId = {0}
where ImageId = {1}";
StringBuilder sb = new StringBuilder();
string[] originalIdAndSeqNumberArray = s.Split('|');
foreach (var originalIdAndSeqNumberCombined in originalIdAndSeqNumberArray)
{
var tempArray = originalIdAndSeqNumberCombined.Split(':');
int originalId = Convert.ToInt32(tempArray[0]);
int sequenceNumber = Convert.ToInt32(tempArray[1]);
sb.Append(String.Format(updateQuery, sequenceNumber, originalId));
sb.Append(System.Environment.NewLine);
}
UpdateInDatabase(sb.ToString());
return "Hello World";
}
private void UpdateInDatabase(string updateQuery)
{
SqlDataProvider sqd = new SqlDataProvider();
string ConnectionString = sqd.ConnectionString;
SqlConnection conn = new SqlConnection(ConnectionString);
SqlCommand command = new SqlCommand(updateQuery, conn);
command.CommandText = updateQuery;
conn.Open();
command.ExecuteNonQuery();
conn.Close();
}

What status code does the ajax call return?
To me it looks like a 500. You are building an update statement that after a few iterations will look something like this
update dnn_Table_1 set SortId = 3 where ImageId = 2update dnn_Table_1 set SortId = 2 where ImageId = 4update dnn_Table_1 set SortId = 7 where ImageId = 6
That just won't work. Try eihter constructing the SQL update differently or move UpdateInDatabase into the foreach loop.
There might be other issues which I didn't spot, but this might be a starting point.
Hope that helps
