I was recently doing some work on a website which has a mixture of older Classic ASP pages and ASP.NET Web Forms pages and ran into problems with custom error pages.

yairEO's Tagify is a great implementation of a tag component, being very lightweight and using in-built browser behaviour where possible. Here's how I get get suggestions via AJAX rather than a fixed whitelist.

Here's ten things every web developer should be aware of and avoid.

Fixed navbars – that stay at the top of the screen at all times – are common and useful, but sometimes annoying as they can block the top part of the page (sometimes obscuring page anchors).

In response to a request, I have made some improvements to the modified version of Mediademon's Simple jQuery Plugin To Create Pinterest Style Grid Layout - Pinterest Grid.

If you have an ASP.NET Web Forms page with multiple UpdatePanels and multiple UpdateProgress controls, sometimes you may want one or more UpdateProgress controls associated with a specific UpdatePanel, and one or more UpdateProgress controls that have no association with an UpdatePanel so are shown when any UpdatePanel is updated.

I still haven't given up on my belief that there is a place for a new programming language/environment where your application database logic are in a single system.

I recently needed to change a client's website to send emails using Amazon SES and encountered a few issues.

If you use Bootstrap 4 cards and apply one of the outline classes to add some colour you will find the header and footer are still grey, which doesn't look right.

What is WDIMPFS? A server with Windows, a DNS server, IIS, a Mail server, a control Panel of some sort, an FTP server and SQL Server.

This posts stems from my own curiosity. It's a question not a statement. I've been developing in ASP.NET for many years and I like it. I've dabbled a bit in PHP and there are some things I like and some I don't like, but maybe I haven't immersed myself in it enough to know what's great about it.

Lately I've been looking at options for hosting various Classic ASP and ASP.NET websites that I am responsible for. Some are hosted on VPS and some are on shared hosting plans with various providers. I'm looking at Microsoft Azure Pack hosting from Gearhost, Everleap and Applied Innovations.

This post is not meant to be a review of Arvixe, it is to describe the unusual way that Arvixe configure their shared and VPS Windows servers.

I recently needed to show a video on a web page that needed to take the full width of the container (in this case, the full screen width) but keep a consistent height.

Although you can easily create inline checkboxes and radio buttons using ASP.NET CheckBoxes and RadioButtons using Bootstrap's checkbox-inline and radio-inline classes, it's not so easy with ASP.NET CheckBoxList and RadioButtonList controls.

I'm not ready to give up on this concept.

I came across an issue where I was setting Page.Title in my ASPX page's Page_Load event, but it was appearing blank when I was attempting to retrieve the value in the MasterPage's Page_PreRender event.

Although probably no one cares about Classic ASP, except those who still need to support it, I was refreshing my memory today on how to use classes in Classic ASP and found a couple of options for simulating constructors with parameters.

It's not often I wish such bad fortune on a new innovation but I am wishing Accelerated Mobile Pages (AMP) dies a quick death.

When I was looking for an alternative to Masonry to produce a responsive Pinterest style grid that was a lot simpler and lighter weight I came across this jQuery plugin on www.jqueryscript.net that is very simple and works well. However, It has a few issues which I needed to fix before I could use it.

Isn't it nice how search engines show a brief section of content with your search terms highlighted in search results?

Recently I've been researching and experimenting with alternate methods to various things involving development, particularly database access, and have come to the conclusion that the systems that we have evolved to today are not ideal.

Any website other than a very simple one uses a database these days, right? Well then why is there a separation between web server and database server? Surely there has to be an advantage in integrating these two systems into one?

I've been looking forward to the release of Bootstrap 4 and finally an Alpha version has been released.

I recently needed to display an implied consent EU cookie law message on a website which uses Bootstrap 3.x and jQuery.

As of July 2015, many of my Classic ASP websites have started logging strange errors, either 80004005 or not reporting any error code at all.

As much as I thought my simple JavaScript solution for responsive web design without media queries was a good idea (and still has a place), I have updated my blog to using the Bootstrap 3 framework.

I have been working on an ASP.NET Web Forms project that is being converted to Bootstrap 3 and have run into a few issues with Modals.

Following on from my last post about improving Bootstrap styling and accessibility for ASP.NET RadioButtonLists and CheckBoxLists, in this post I offer a solution for styling these controls within Bootstrap horizontal forms.

I have wanted to add protection from vavigating away from some of my web forms but most of the solutions I have seen do not work well with ASP.NET with it's many possible ways of posting back and AJAX using Update Panels.

My latest web project is Ghost Tour Bookings, a website where ghost tours are advertised and people can make enquiries or book the tour.

If you come across a problem where you set the Visible property of an ASP.NET control to true in a code behind file, but even when you debug it still shows the value as being false then the problem is most likely to be that the control is inside another control such as a Panel or PlaceHolder that has its Visible property set to false.

I recently experienced an issue with an ASP.NET Web Forms page with various UpdatePanels. The page has two DropDownLists, the selection of one results in populating of possible values in the other, and the selection of the other results in enabling of a Button. Then if the Button is clicked the user is redirected to another website, based on their selection.

Web forms makes it really easy to create a simple website, but it is also really difficult to crate a complicated website. These are some of the things you will need to know sooner or later.

Over fifteen years of developing for the web, I've learned some lessons the hard way. There are some things they don't teach you in books and tutorials.

Looking for an inexpensive web hosting company for a ASP.NET (or Classic ASP) website? I have experience with five of the most popular hosting company's shared hosting plans: Hostek, Arvixe, SmarterASP, ASPnix and RDO Servers.

I was really excited when I first found fiverr.com. Here was a site where you could get almost anything done for $5 (US).

This is a list of ASP server side controls that require or do not require to be nested inside of a server form (form runat="server").

Personally I can never remember which of the Request object properties I need to use to get the requested URL or certain parts of the requested URL.

On database-driven websites it is commonplace to execute multiple database queries to generate just one page. For example, on the home page of an ecommerce website you might get a list of categories, a list of banner advertisements to display, a list of featured products, and a list of top selling products. I investigate whether it was more efficient to put these multiple queries into one stored procedure and use the SqlDataReader's Next Result method to get the data all in one go.

If writing database queries in SQL in Classic ASP for SQL Server, rather than using ADO or parameterised queries, you can use these functions to correctly format your data and protect against SQL injection.

If you are using Entity Framework and have received this error message and have been frustrated by not being able to see what the actual problem is in Visual Studio then there is a simple solution.

Developing a secure membership system can be complicated as there are many potential danger areas that you must be aware of. In this post I hope to cover all of the areas you need to think about and plan for.

If you use ASP.NET UpdatePanels, most of the time you want to maintain the window scroll position but there are occasions when you don't want to scroll back to the top or to a specific control.

I often use the standard ASP.NET ValidationSummary to display form validation error messages but often struggle what to write for the Headertext property.

I have put up with a bug in Visual Studio for some time, but recently finally got around to reporting it. I need your vote to get this bug fixed.

Looking at the Google search results, it seems that there has been plenty of demand to share Session values between Classic ASP and ASP.NET. This is usually a result of supporting legacy Classic ASP.NET with new development in ASP.NET.

Review of webSupergoo's ABCPDF.

Solution to the ASP.NET UpdatePanel lost focus on post back issue.

Many or perhaps most websites have the need for a search facility to search the website content or other things like products. Ideally you want an intelligent search, a bit like a search engine, where search results are ordered by relevancy, misspellings are tolerated, and maybe even word stemming is used (so a search for "teach" also returns results for "teacher", "teaches", "teaching", "taught", etc).

Following on from my previous article on responsive design without media queries, I have been looking for how to handle the problem of image size and display in responsive design.

...Or an alternative to media queries for responsive design I really like the concept of responsive design, and I have read a lot of the positive stuff about it, and also read a lot of the negative too.

This is the biased opinion of a developer of custom-written applications.

Following up on my previous article about ASP.NET HtmlForms, this sample code illustrates how to handle file uploads.

There are times when I really like ASP.NET and times when I don't. Usually the times that I don't are when I don't have as much control over the final HTML markup as I would like, or when I look at the amount of JavaScript, ViewState and other markup that ASP.NET has added.

I needed to add a login with Facebook button to a website and wanted a simple solution that would check whether the user successfully logged in and return their email address and name. I considered using the C# SDK but couldn't find much in the way of documentation or samples to accomplish this task.

I recently needed a Javascript function to truncate text to fit a container such as a DIV, not just in width but in height. I found plenty of functions that truncate to width but couldn't find anything by height so I created this Jquery plugin that does the job. Please note that it does not handle HTML so if HTML content is truncated it may truncate mid-tag and break the display.

This is how you can connect to a MySQL database from ASP.NET Web Pages (Razor).

Using Linq to SQL and need to order by NULLS last?

When developing websites most of them have common elements like headers, footers and navigational menus that are common throughout the site. In Classic ASP we mostly use multiple server side includes to accomplish this. I like ASP.NET master pages and this page details the technique I use to achieve something similar in Classic ASP.

This Classic ASP function will convert your old 10 digit ISBN numbers to the new ISBN-13 standard. It requires one parameter: either a 9 or 10 digit ISBN-10.

URL rewriting is usually used to make a URL for a dynamic web page more presentable, either for the reader or for search engines.
