The controller is being called 3 or 4 times, probably because the code is watching Change, KeyDown, Paste, and Input:
$("#searchField").on('change keydown paste input', function () {
Is this the right way to do this?

It's the right way to do it if you want to update the grid when any of those events happen. 
If you want to prevent the grid from updating too frequently, you'll need to "buffer" the events, and only trigger the handler after a pause. This answer[^] has an example of how to do that:
function debounce(fn, delay) {
var timeout;
return function () {
var context = this,
args = arguments;
clearTimeout(timeout);
timeout = setTimeout(function () {
fn.apply(context, args);
}, delay || 250);
};
}
...
$("#searchField").on('change keydown paste input', debounce(function () {
...
}));
With that in place, the function to update the grid will only fire after a ¼-second pause in keystrokes.

I would like to put a search field above a WebGrid, and also provide some combo boxes for filtering.
I've never done this before. Can someone who's done this point me in the right direction please?
Thank you

I haven't used WebGrid, but Ehsan Sajjad posted a great series of articles on using the DataTables[^] jQuery plugin from MVC to do this sort of thing back in March:
Alternatively, if you want to keep it simple, you'll just need to add a <form> with the relevant fields for filtering, and have an action that takes parameters for those fields and filters the data accordingly. It shouldn't be too difficult to set up.

My website is built with angular js. when i submitted sitemap only home page is indexed and remaining pages are not indexed. I already changed all my page urls # to #! . please suggest me .
|

|
|

Maybe you have a robots.txt file that is telling the search engine not to request other pages?
The difficult we do right away...

I have a page that receives a notification from a SignalR server when either a new row is added to a table or an existing row is changed. The data is displayed in a WebGrid.
proxy.on('notifyAllClientsOfChanges', function (model) {
var $row = $(".webgrid-table").find("span[data-row-id='" + model.RowId + "']").closest("tr");
if ($row.length) {
updateRow($row, model)
}
else {
createNewRow(model);
}
function createNewRow(model)
{
var table = document.getElementById('MyGrid');
var new_row = table.rows[0].cloneNode(true);
new_row.cells[0].value = model.RowId;
new_row.cells[1].value = model.SiteId;
new_row.cells[2].value = model.InstrumentId;
new_row.cells[3].value = model.TowerLocation;
new_row.cells[4].value = model.BayLocation;
new_row.cells[5].value = model.BaySerialNo;
new_row.cells[6].value = model.BayStatus;
new_row.cells[7].value = model.AccessionId;
new_row.cells[8].value = model.Result;
new_row.cells[9].value = model.AssayName;
new_row.cells[10].value = model.Started;
new_row.cells[11].value = model.Completed;
new_row.cells[12].value = model.TestSummary;
table.appendChild(new_row);
}
function updpateRow($row, model)
{
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);
}
});
The code above fires when a new row is added to the database or changes are made to an existing row. The code does work, but I don't see the additions or updates appear in the grid. If I refresh the page then the controller is called again and the entire data set is returned, which is what I'm trying to avoid.
So, what I want is to see row additions or changes in the WebGrid. How can I refresh the WebGrid without going back to the server?
Thank you

Any errors in the browser console?
Have you tried adding some console.log calls to make sure your code is being called?

Is it just the new rows that aren't appearing?
The code looks like it should work, but to be pedantic, the new row should be appended to the <tbody> rather than the <table>:
table.tBodies[0].appendChild(new_row);
It probably won't make a difference, unless your CSS is specifically targeting the tbody element.

I think there's a problem with setting the new_row.cells[i].value - it's not a standard property for a table cell, so it doesn't change the content: Demo[^]
If you use innerHTML or innerText, the value will be updated: Demo[^]
But you'll still have the problem of the <span> elements disappearing for the new rows. As I said yesterday, I'd be inclined to combine the add and update code, and use jQuery to set the text of the spans instead.
You might also want to check which row you're cloning - I suspect rows[0] will be the header row.

Well, first let me say Many Thanks for all your help so far. I've come a long way and I now have a functional app. I am now seeing new rows appear in the WebGrid.
However, one final issue:
The new row appears at the bottom of the grid. The data is returned from the server in descending order by the TestStarted column. See this image.
Here's the JS I have so far incorporating all the help you've given me, including the console.log entries shown in the image I linked.
proxy.on('notifyAllClientsOfChanges', function (model) {
console.log("notifyAllClientsOfChanges called");
var $row = $(".webgrid-table").find("span[x-RowId='" + model.RowId + "']").closest("tr");
console.log(model.RowId);
if (!$row.length) {
var table = document.getElementById('MyGrid');
console.log("TABLE");
console.log(table);
var len = table.rows.length;
console.log("len = " + len);
var new_row = table.rows[1].cloneNode(true);
console.log("new_row");
console.log(new_row);
new_row = table.tBodies[0].appendChild(new_row);
console.log("new_row");
console.log(new_row);
$row = $(new_row);
$row.find("span[x-RowId]").data("rowId", model.RowId).text(model.RowId);
}
console.log("SETTING ROW VALUES");
$row.find(".x-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);
console.log("DONE");

That's a bit confusing - you're looking for an attribute called x-RowId, but you're updating the data-row-id attribute. It would probably be better to stick with the data-row-id attribute, since that's the standard way of associating extra data with an element.
There's also no need to update the row ID for an existing row.
proxy.on('notifyAllClientsOfChanges', function (model) {
console.log("notifyAllClientsOfChanges called");
var $row = $(".webgrid-table").find("span[data-row-id='" + model.RowId + "']").closest("tr");
console.log(model.RowId, $row);
if (!$row.length) {
var table = document.getElementById('MyGrid');
console.log("TABLE", table);
var len = table.rows.length;
console.log("len = ", len);
var new_row = table.rows[1].cloneNode(true);
console.log("new_row", new_row);
new_row = table.tBodies[0].appendChild(new_row);
console.log("new_row", new_row);
$row = $(new_row);
$row.find("span[data-row-id]").data("rowId", model.RowId).text(model.RowId);
}
console.log("SETTING ROW VALUES");
$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);
console.log("DONE");
}
It looks like the server is sending 0 as the RowId, so you'd need to fix that on the server.
The appendChild method will always insert the element at the end of the specified parent. If you want to insert it at a specific position, you'll need to find the row that should immediately follow it, and use insertBefore[^] to add the node. Something like this:
var new_row = table.rows[1].cloneNode(true);
console.log("new_row", new_row);
var before_row = null;
var before_value = null;
$(".webgrid-table tr").each(function(){
var value = $(this).find(".x-Started").text();
if (value < model.Started) {
if (!before_row || before_value < value) {
before_row = this;
before_value = value;
}
}
});
if (before_row) {
new_row = table.tBodies[0].insertBefore(new_row, before_row);
}
else {
new_row = table.tBodies[0].appendChild(new_row);
}
console.log("new_row", new_row);
If you can't convert the text value of the x-Started span to an appropriate type for sorting, you'll need to use another data- attribute to store and retrieve a sortable value.

I noticed that after I posed. Looking at that now.

genesis child theme- I have added a new page Template and need a little help. The template will allow me to style with old divs but when I try to add new styles to my style.css it will not pick up the changes.
Do I need to add a complete new style sheet to or do i need some type of new code in function.php?
|

If there is another stylesheet with the same classes or style names which are overriding what you put in. You can override the cascading order by using !important.
Please see this link for information on the order in which stylesheets are loaded:
Assigning property values, Cascading, and Inheritance[^]
There is also an example of how to use !important on that page directly below where it describes which order stylesheets are loaded.
Hope this is what you are looking for.

[UPDATE]
I solved this. I set the WebGrid's Id by doing
htmlAttributes: new { id = "MyGrid" }
then doing this in the JS
var table = document.getElementById('MyGrid');
[UPDATE]
I'm trying to insert a new row into a WebGrid. I'm getting an error "Uncaught TypeError: Cannot read property '1' of undefined"
My WebGrid code
@using (@Html.BeginForm("Index", "Home"))
{
@{
var grid = new WebGrid(Model, rowsPerPage: 10, ajaxUpdateContainerId: "divData", canPage: true);
@grid.GetHtml(
tableStyle: "webgrid-table",
headerStyle: "webgrid-header",
footerStyle: "webgrid-footer",
alternatingRowStyle: "webgrid-alternating-row",
selectedRowStyle: "webgrid-selected-row",
rowStyle: "webgrid-row-style",
mode: WebGridPagerModes.All,
columns:
grid.Columns
(
grid.Column(columnName: "RowId", header: "Row Id", format: @@item.RowId),
grid.Column(columnName: "SiteId", header: "Site Id", format: @@item.SiteId),
))
}
}
and my JavaScript
function createNewRow(model)
{
var table = document.getElementById('divData');
var new_row = table.rows[1].cloneNode(true);
var len = table.rows.length;
new_row.cells[0].innerHTML = len;
new_row.cells[1].value = model.SiteId;
new_row.cells[2].value = model.InstrumentId;
new_row.cells[3].value = model.TowerLocation;
new_row.cells[4].value = model.BayLocation;
new_row.cells[5].value = model.BaySerialNo;
new_row.cells[6].value = model.BayStatus;
new_row.cells[7].value = model.AccessionId;
new_row.cells[8].value = model.Result;
new_row.cells[9].value = model.AssayName;
new_row.cells[10].value = model.Started;
new_row.cells[11].value = model.Completed;
new_row.cells[12].value = model.TestSummary;
table.appendChild(new_row);
}
There are rows in the table, so why doesn't the Rows collection exist? I can see row data in the Console.
If it's not broken, fix it until it is.

I need technical advice on this matter. How to save form data to a disk file(Excel, text, XML format). Web server is not belongs to me. I just fill form for a web site. I need to use same data later to make comparisons and analyze. I need this to do to avoid duplicate data entry. Any method that can be used?. Any possibility to write memory resident program to to figure this out?. Thanks. 😊😊

Client side and Server side are are deliberately quite isolated. If you don't have write access to the server then you're not going to make any changes to it that those who control it do not want you to make.
If you had write access to the web server then you'd still need a server-side method to do this.
I, for example, use php[^]. There's a lot to this and you'll need to study it.

Hi Balboos,
I totally agree and understand your point. I have no write access to server end components/materials. I am at clients end. is there any possibility to run a routine/program at client end(my pc) that record all data I entered to the web site(I mean record all keyboard entries locally). This may be crazy question, but if I could figur out a method to do so I can save lot of my time to spent my time to repeat same data twice.
Thanks in advance.
Note : I am good at php/c#/Delphi coding.
