I would suggest you edit your question and show the code that can get the table id. Getting the table's parent is likely very trivial after that.

Thank You for the reply. Here is my code.
' Get all tables in the document
Dim tables As HtmlAgilityPack.HtmlNodeCollection = main.DocumentNode.SelectNodes("//table")
' Iterate all rows in the first table

Dim rows As HtmlAgilityPack.HtmlNodeCollection = main.DocumentNode.SelectNodes("//table[@id='workorders']//tr")
' Dim rows As HtmlAgilityPack.HtmlNodeCollection = main.DocumentNode.SelectNodes("tr")

' Iterate all rows in the first table
For k = 0 To rows.Count - 1
' Iterate all columns in this row
Dim cols As HtmlAgilityPack.HtmlNodeCollection = rows(k).SelectNodes("th|td")
' Dim cols As HtmlAgilityPack.HtmlNodeCollection = rows(k).SelectNodes("tr")
If cols IsNot Nothing Then
For j = 0 To cols.Count - 1
' Get the value of the column and print it
Dim value As String = cols(j).InnerText
If value = "Project Name/Work Order" Then
Foundwork = True
End If
Next
End If
Next

so I have the following code which I would like to adapt to take data straight from my sql database.

The code so far is:

@{
    Layout = "~/Views/Shared/_Layout.cshtml";

    var myChart = new Chart(width: 600, height: 400, theme: ChartTheme.Green)
.AddTitle("Product Life Cycle")
.AddSeries(
name: "Employee",
chartType: "Spline",
xValue: new[] { "2003", "2004", "2005", "2006", "2007", "2008", "2009", "20010", "2011", "2012", "2013", "2014", "2015", "2016", "2017", "2018", "2019", "2020", "2022", "2023", "2024", "2025", "2026" },
yValues: new[] { "5.40", "16.17", "109.46", "347.87", "791.62", "1865.88", "2899.26", "4083.32", "4693.27", "6442.52", "8053.77", "9388.84", "9964.89", "10776.18", "4931.34", "2582.54", "752.53", "150.83", "77.87", "31.21", "0.33", "0", "0" })
.Write();
}

I would like to assign xValue and yValue to a table example TBL_MYdata and with the fields ConDate and ConUnits. I am very new to C# and realy need to sort this soon. Many thanks for any help available

Loading data from the database is best done in the controller, rather than the view.

Assuming you're using raw ADO.NET to access the database, something like this should work:

Controller:

public ActionResult YourAction()
{
    var xValues = new List<string>();
    var yValues = new List<string>();
    
    using (var connection = new SqlConnection("... YOUR CONNECTION STRING HERE ..."))
    using (var command = new SqlCommand("SELECT ConDate, ConUnits FROM TBL_MYdata ORDER BY ConDate", connection))
    {
        connection.Open();
        
        using (var reader = command.ExecuteReader(CommandBehavior.CloseConnection))
        {
            while (reader.Read())
            {
                xValues.Add(Convert.ToString(reader["ConDate"]));
                yValues.Add(Convert.ToString(reader["ConUnits"]));
            }
        }
    }
    
    var model = new Chart(width: 600, height: 400, theme: ChartTheme.Green)
        .AddTitle("Product Life Cycle")
        .AddSeries(name: "Employee", chartType: "Spline", xValues: xValues.ToArray(), yValues: yValues.ToArray());
    
    return View(model);
}

View:

Razor

@model Chart
@{
    Layout = "~/Views/Shared/_Layout.cshtml";
    Model.Write();
}

Trying to open a pdf file in a new Tab on Chrome browser - not happening

Re: Trying to open a pdf file in a new Tab on Chrome browser - not happening

3-Jan-20 5:59

I have Get Method which I am expecting to open a pdf file in a new browser tab, but its not happening - below is the code

public void GetDoc(int id)
    {
        string fileInfo = "ID=[" + id + "] ";
        try
        {
            var file = this.DomainLogicUnitOfWork.UploadedDocumentManager.GetById(id);
            fileInfo = "FILENAME=[" + file.FileName + "]";

            Response.Clear();
            Response.ContentType = file.FileContentType;
            Response.AppendHeader("content-disposition", "attachment; filename=" + file.FileName);
            Response.OutputStream.Write(file.DocumentImage, 0, file.DocumentImage.Length);
            Response.Output.Flush();
            Response.End();
        }
        catch (Exception ex)
        {
            LogHandler.LogError(4617, "Error Downloading Document " + fileInfo, ex);
            throw ex;
        }
    }

My url is opening correctly: http://localhost:xcxcxcx/Upload/GetDoc?id=1088 and it gives a warning when click on the start of the browser address and one more thing is the Word and other documents are being downloaded fine - means they are working fine but problem is just with PDF files. Any suggestions or ideas -
thank you all friends.

Re: Trying to open a pdf file in a new Tab on Chrome browser - not happening

There are some browser settings that can control whether or not files are opened in a new tab so you don't have complete control over it.

Also, this code runs in the context of the existing page and will return to the same page. I do not think there is a way to do it with code like this.

You can create a hyperlink and set it to open in a new tab.
You can also change the button or whatever it is that fires this event to open a new window and pass in a url that then calls this code.

Re: Trying to open a pdf file in a new Tab on Chrome browser - not happening

3-Jan-20 6:50

It is fixed by change the AppendHeader as below

if (file.FileContentType.ToLower() != "application/pdf")
                   Response.AppendHeader("content-disposition", "attachment; filename=" + file.FileName);

But I got another question - is there any way I can let the user when saving the file - give him the file name that has come by default - any help please? Thank you.

It's my understand that will make it download as an attachment rather than display inline. If that made it open in a new tab for you, that's good, but like I said I don't think you can control it 100%. Someone's browser settings can change that behavior.

simpledeveloper wrote:

I'm not sure what you mean. In your code you specified a file name.

OK - nice, is there anyway I can allow the user to download the file rather than opening in a new browser? How can I do that? It will be a great help for me.

How can I change this statement for pdf to be able to download? Any help regarding this buddy? It will be a great help - thank you.

Attachment means it will download. But again, some browsers have settings that can affect that.

If it is chrome? Is there something we can do it from server side code buddy? Yeah now I am getting it - why isn't it doing it - thanks for helping me my friend.

Sorry, I do not know. It's been years since I worried about this issue so I don't know what the settings look like today.

I believe the only thing you can do is to add the attachment header info which you already did.

Yes I did see it - its working fine with IE, its only giving problem with Chrome - so any ideas from other users here also helpful - I will investigate a little bit about it.

How I can insert data into gridview without use data source???

Enclosing within the double quotes resolved the problem like in this one:
