$row.find("td") That returns all of the <td> elements within the specified row.
.eq(1) That reduces the set to the second <td> element in the row.
.eq() | jQuery API Documentation[^]
.text(model.SiteId) That sets the text of the matched element.
If your row is particularly complex, it might be easier to use the same Handlebars.js[^] template you're using for the new row, and use $row.replaceWith(newRow)[^] to replace the row, rather than trying to update each cell.

If you look at this SignalR example, about halfway down, they seem to be doing something similar to this.
They are hard coding in the HTML for a row. This sounds like what I would need in the createNewRow function you posted. Im I correct on this?

Yes, that would probably work for a simple row template.
But they're building the entire table in Javascript, so they can use data- attributes on the <tr> elements to identify the row. There isn't any way to do that with the WebGrid helper, so you'd still need to include the <span data-row-id="..."> within a column, and use that to find the row to update.

Using what you've taught me, as well as examples like this, I now have this
The Table
I added SPAN tags to the table rows
grid.Column(columnName: "RowId", header: "Row Id", format: @<text><span data-row-id="@item.RowId">@item.RowId</span></text>),
grid.Column(columnName: "SiteId", header: "Site Id", format: @<text>@item.SiteId</text>),
grid.Column(columnName: "Instrument", header: "Instrument", format: @<text>@item.InstrumentId</text> ),
grid.Column(columnName: "TowerLocation", header: "Tower", format: @<text>@item.TowerLocation</text>),
grid.Column(columnName: "BayLocation", header: "Bay Location", format: @<text>@item.BayLocation</text>),
grid.Column(columnName: "BaySerialNo", header: "Bay Serial #", format: @<text>@item.BaySerialNo</text>),
grid.Column(columnName: "BayStatus", header: "Bay Status", format: @<text>@item.BayStatus</text>),
grid.Column(columnName: "AccessionId", header: "Accession ID", format: @<text>@item.AccessionId</text>),
grid.Column(columnName: "Result", header: "Result", format: @<text>@item.Result</text>),
grid.Column(columnName: "AssayName", header: "Assay Name", format: @<text>@item.AssayName</text>),
grid.Column(columnName: "TestStarted", header: "Started", format: @<text>@item.Started</text>),
grid.Column(columnName: "TestCompleted", header: "Completed", format: @<text>@item.Completed</text>),
grid.Column(columnName: "TestSummary", header: "Test Summary", format: @<text>@item.TestSummary</text> )
The JavaScript Code
var $row = $(".webgrid-table").find("span[data-row-id='" + model.RowId + "']").closest("tr");
if ($row.length) {
var col01 = $row.find(".x-SiteId").text(model.SiteId);
var col02 = $row.find(".x-InstrumentId").text(model.InstrumentId);
var col03 = $row.find(".x-TowerLocation").text(model.TowerLocation);
var col04 = $row.find(".x-BayLocation").text(model.BayLocation);
var col05 = $row.find(".x-BaySerialNo").text(model.BaySerialNo);
var col06 = $row.find(".x-BayStatus").text(model.BayStatus);
var col07 = $row.find(".x-AccessionId").text(model.AccessionId);
var col08 = $row.find(".x-Result").text(model.Result);
var col09 = $row.find(".x-AssayName").text(model.AssayName);
var col10 = $row.find(".x-Started").text(model.Started);
var col11 = $row.find(".x-Completed").text(model.Completed);
var col12 = $row.find(".x-TestSummary").text(model.TestSummary);
}
else {
var table = document.getElementById('divData');
var new_row = table.rows[0].cloneNode(true);
var len = table.rows.length;
new_row.cells[0].innerHTML = len;
new_row.cells[1].value = mode.SiteId;
new_row.cells[2].value = mode.InstrumentId;
new_row.cells[3].value = mode.TowerLocation;
new_row.cells[4].value = mode.BayLocation;
new_row.cells[5].value = mode.BaySerialNo;
new_row.cells[6].value = mode.BayStatus;
new_row.cells[7].value = mode.AccessionId;
new_row.cells[8].value = mode.Result;
new_row.cells[9].value = mode.AssayName;
new_row.cells[10].value = mode.Started;
new_row.cells[11].value = mode.Completed;
new_row.cells[12].value = mode.TestSummary;
table.appendChild(new_row);
}
Any reason this technique would not work?

It looks close, but I think you'd end up losing the <span data-row-id="..."> on the new rows.
I'd be inclined to try to combine the two branches:
var $row = $(".webgrid-table").find("span[data-row-id='" + model.RowId + "']").closest("tr");
if (!$row.length) {
var table = document.getElementById('divData');
var len = table.rows.length;
var new_row = table.rows[len - 1].cloneNode(true);
new_row = table.appendChild(new_row);
$row = $(new_row);
$row.find("span[data-row-id]").data("rowId", model.RowId).text(model.RowId);
}
$row.find(".x-SiteId").text(model.SiteId);
$row.find(".x-InstrumentId").text(model.InstrumentId);
$row.find(".x-TowerLocation").text(model.TowerLocation);
$row.find(".x-BayLocation").text(model.BayLocation);
$row.find(".x-BaySerialNo").text(model.BaySerialNo);
$row.find(".x-BayStatus").text(model.BayStatus);
$row.find(".x-AccessionId").text(model.AccessionId);
$row.find(".x-Result").text(model.Result);
$row.find(".x-AssayName").text(model.AssayName);
$row.find(".x-Started").text(model.Started);
$row.find(".x-Completed").text(model.Completed);
$row.find(".x-TestSummary").text(model.TestSummary);

I don't know where is the Null value and don't know how to catch it since the code display error on line in which i include script file

Null Reference Exception particularly means that the object you are currently using, does not exist in the memory. You can easily get rid of this error in many ways,
var obj = new ObjectType();
if(obj == null) {
} else {
}
var value = obj?.Property;
Yet, there are many other ways to hide this. But in my own opinion, if you encounter null reference exception, then you should not try to avoid it, but have a look at why was it there in the first place. The object, in your Charting.Axis etc, they are null, I would say, Axis was null as you are trying to call a function on it. So, do check them. And properly create an instance of them so that this error can go away.

1) An unformatted code-dump is not a question.
2) Storing the username and password in cookies is an EXTREMELY bad idea. Please tell us which site(s) your code will be deployed on, so that we can blacklist them.
3) Look at the cookie names you're setting, then look at the cookie names you're trying to read.

I know that this question probably have been asked many times before but things changes over time.
We are developing a huge website in size comparison to facebook. It will be very unique design wise and should be pixel perfect from the design. As we see it most of the features in the bootstrap framework will only take resources, as much of those will not be used or highly customized using less in our case.
Is bootstrap still really the right way to go for this project or should we just base it on normalize?
We know the development will be heavily decreased with bootstrap but that doesn't matter.

Start by giving up on that unrealistic goal. 
Trying to make the site a "pixel perfect" match for a design image is hard enough in a single browser at a fixed resolution. Once you start throwing in multiple browsers at different resolutions, it becomes virtually impossible. So unless you're going to add a 90's style footer saying "This site is best viewed in Internet Explorer 4 at 1024x768", it's not going to work.
Member 13110077 wrote: much of those will not be used or highly customized
So either customise Bootstrap[^], and remove the components you're not going to use; or don't use Bootstrap.
If you're not going to use most of the features from Bootstrap, then it wouldn't make sense to use Bootstrap. There are other lightweight frameworks available that you could base your site on - eg: W3.CSS Home[^]. Or you could build your CSS from scratch, which would give you complete control.
There's no point fighting to adapt a framework that isn't a good fit for your requirements.

Thanks for your answer. Do you have any examples of some frameworks that just takes care of these basic problems as normalize does that should be used even though i am writing my own css?
|
|
|
|
|
Normalize will give you a good baseline to start from, with no extraneous fluff.
If you want to start with a framework, W3.CSS[^] seems to be relatively light-weight (4.78Kb), and seems to include quite a few utility classes.

I want to learn how to create my own themes in Wordpress, and I've also read about (and separately been recommended) using the Bootstrap framework to do so.
Now, I do have I would say beginner/intermediate level HTML experience, I've obviously used Dreamweaver and, years ago, Frontpage, to design websites. I can modify Wordpress themes to make appearance difference, I know my way around a CSS stylesheet, but I'm certainly not at the level of being able to create a theme from scratch. My HTML knowledge is pretty archaic also.
