string lbText = ((LinkButton)grvSpeakers.HeaderRow.Cells[i].Controls[0]).Text;
The message suggests that the i index is invalid for the number of cells in the row, or Controls does not contain any items. You need to use the debugger to find out which one is the problem.

Hi
I have a project developed in ASP.net MVC. Need to print to a receipt printer connected with Network IP. Can you share the code.
Thanks

If the printer is connect to the server, and is available to the user account which your application pool is configured to run as, then you might be able to print to it.
If the printer is connect to the client, then all you can do is issue a window.print(); command in Javascript, and hope that the user picks the correct printer, and that the printed output of the current document matches your requirements.
There is no way to print to a client printer from server-side code, and client-side code deliberately has very little control over printing for security reasons.

Usually you generate a PDF in the correct printer format, present the PDF for download, open the PDF and print.

I had a break in between customer projects and decided to take a stab at upgrading my app from Angular V7 to V10, NetCore V3.1 to V5. Had a hell of a time composing my package.json to not produce any version errors. In my last version of my app I was using ngtools/webpack which seemed to just take care of everything for me. But looking at documentation on the internet, it looks like Webpack is back in style now.
I'm confused on a few things, and thought maybe a passer by may set me straight with some proper info. So I'm suppose put my webpack.config.js file in the root of my .net core project so I can build it using debug. Yet if I want to test my webpack file, it needs to be in the clientapp folder of the root project.
I started writing a new webpack.config.js, and many articles pointed to modifying my angular.json file to run @angular-builders/custom-webpack instead of @angular-devkit/build-angular/@angular-devkit/build-webpack.
Ran into that error on debug and build, "fail, Microsoft.AspNetCore.SpaServices[0], and was wondering if anyone had any insight into this. I do have the modules in node_modules.
fail: Microsoft.AspNetCore.SpaServices[0]
<s> [webpack.Progress] 25% building 32/34 modules 2 active C:\Users\jkirk\source\repos\jkirkerx\jkirkerx\ClientApp\node_modules\babel-loader\lib\index.js??ref--7-0!C:\Users\jkirk\source\repos\jkirkerx\jkirkerx\ClientApp\node_modules\@angular-devkit\build-angular\node_modules\webpack\hot\log.js
I tried a lot of different things, just really need to get straighten out on the base or foundation of webpack, then I can fix one issue at a time.
I upgraded to NetCore 5 and that didn't do anything for the error above. Same thing as NetCore 3.1

I'm pretty close to solving it now.
Down to 1 error now, Can't find Webpack, and can now clearly see the error in the webpack-dev-server.
I installed done-webpack-plugin to halt on errors and give me a description.

Because you're posting in a forum which is designed for answering other people's questions. But instead of answering someone else's question, you've made up your own question and posted an answer to that.
It's similar to a salesman who knocks on your door to try to sell you a set of encyclopaedias - he obviously won't receive the same welcome as the plumber you called to come and fix your broken toilet.
As I said, if you want to publish this information here, then you need to post it as a tip. There is no equivalent section on StackOverflow, so you can't publish it there.
The other alternative would be to set up your own blog.

Additionally, the downvotes might be related to bad spelling, bad formatting, wrong grammatic and specially with the impression you give, that you don't give a crap about the quality and correctness of your posts.
An don't get me wrong, I can understand if you are not a native english speaker, because neither I am native speaker. But only because you can't speak well a language, it doesn't mean that you can't try to speak that language properly.

I am trying to work on autocomplete using jQuery (using a tutorial from here - link,
The problem is that it works fine when I add the following line:
@{
Layout = null;
}
but when I remove it, I have the error about autocomplete function not being found.Is there way around this? I know that it is related to the scripts conflinct in _layout page, but I don't know how to resolve it and I'd like to have my menu layout.

You haven't included the required script references properly, or you've included them in the wrong order.
Since we can't see what you've done, we can't tell you how to fix it.

I load the script from external file and the order is:
<script src="https://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.10.0.min.js" type="text/javascript"></script>
<script src="https://ajax.aspnetcdn.com/ajax/jquery.ui/1.9.2/jquery-ui.min.js" type="text/javascript"></script>
<link href="https://ajax.aspnetcdn.com/ajax/jquery.ui/1.9.2/themes/blitzer/jquery-ui.css"rel="Stylesheet" type="text/css" />
<script src="~/Scripts/selectAuthor.js"></script>
and the script order in _layout:
in the head section:
<script src="~/Scripts/jquery-3.3.1.min.js"></script>
<script src="~/Scripts/bootstrap.min.js"></script>
<link rel="stylesheet" href="~/Scripts/bootstrap.min.css">
and at the end of section:
@Scripts.Render("~/bundles/jquery")
@Scripts.Render("~/bundles/bootstrap")
<script src="https://ajax.aspnetcdn.com/ajax/jquery/jquery-3.3.1.min.js"
asp-fallback-src="~/lib/jquery/dist/jquery.min.js"

You're loading multiple copies of jQuery, which will never work:
<script src="https://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.10.0.min.js" type="text/javascript"></script>
...
<script src="~/Scripts/jquery-3.3.1.min.js"></script>
...
@Scripts.Render("~/bundles/jquery")
...
<script src="https://ajax.aspnetcdn.com/ajax/jquery/jquery-3.3.1.min.js"
asp-fallback-src="~/lib/jquery/dist/jquery.min.js"
asp-fallback-test="window.jQuery"
crossorigin="anonymous"
integrity="sha384-K+ctZQ+LL8q6tP7I94W+qzQsfRV2a+AfHIi9k8z8l9ggpc8X+Ytst4yBo/hH+8Fk">
</script> You're also loading Bootstrap multiple times.
And you're mixing up the MVC5 approach (@Scripts.Render) with the ASP.NET Core / .NET 5 tag helper approach (asp-append-version, asp-fallback-src).
Simplify your scripts so that you only load each library once. And pick the correct approach for the framework you're using.

I left layout scripts as they are and didn't touch them. For the script part I took one from tutorials. What would you suggest in the terms of making both work fine? For me it doesn't matter much if it is MVC5 approach or ASP.NET core as long as it works.
|
|
|
|
|
Well, it does matter which approach you use - the @Scripts.Render approach won't work in ASP.NET Core / .NET 5, and the asp-append-version approach won't work properly in MVC5. 
(To be precise, the asp-* attributes will be sent as-is in the rendered HTML, and won't have the expected effect in MVC5.)
If you're using MVC5, stick to the @Scripts.Render approach for your bundles, and remove the asp-* attributes from your <script> tags:
Layout:
@Scripts.Render("~/bundles/jquery")
@Scripts.Render("~/bundles/bootstrap")
<script src="~/js/site.min.js"></script>
@RenderSection("scripts", required: false) View:
@section scripts {
<script src="https://ajax.aspnetcdn.com/ajax/jquery.ui/1.9.2/jquery-ui.min.js"></script>
<link href="https://ajax.aspnetcdn.com/ajax/jquery.ui/1.9.2/themes/blitzer/jquery-ui.css" rel="stylesheet" />
<script src="~/Scripts/selectAuthor.js"></script>
}
If you're using ASP.NET Core or .NET 5, use the asp-* attributes instead:
Layout:
<script src="https://ajax.aspnetcdn.com/ajax/jquery/jquery-3.3.1.min.js"
asp-fallback-src="~/lib/jquery/dist/jquery.min.js"
asp-fallback-test="window.jQuery"
crossorigin="anonymous"
integrity="sha384-K+ctZQ+LL8q6tP7I94W+qzQsfRV2a+AfHIi9k8z8l9ggpc8X+Ytst4yBo/hH+8Fk">
</script>
<script src="https://ajax.aspnetcdn.com/ajax/bootstrap/3.3.7/bootstrap.min.js"
asp-fallback-src="~/lib/bootstrap/dist/js/bootstrap.min.js"
asp-fallback-test="window.jQuery && window.jQuery.fn && window.jQuery.fn.modal"
crossorigin="anonymous"
integrity="sha384-Tc5IQib027qvyjSMfHjOMaLkfuWVxZxUPnCJA7l2mCWNIpG9mGCD8wGNIcPD7Txa">
</script>
<script src="~/js/site.min.js" asp-append-version="true"></script>
@RenderSection("scripts", required: false) View:
@section scripts {
<script src="https://ajax.aspnetcdn.com/ajax/jquery.ui/1.9.2/jquery-ui.min.js"></script>
<link href="https://ajax.aspnetcdn.com/ajax/jquery.ui/1.9.2/themes/blitzer/jquery-ui.css" rel="stylesheet" />
<script src="~/Scripts/selectAuthor.js" asp-append-version="true"></script>
}
Either way, make sure you only include each library once in the page, and that you include them in the correct order. Check the "view source" option in your browser to view the rendered output to make sure it's doing what you expect.

It works with the first approach. The only problem is that the dropdown autocomplete menu is not shown directly under the textbox, but rather in the top-left corner.
