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.

It's been a while since I posted one of my rants about eBay but there has been something annoying me for some time now. eBay have a feature where sellers can list multiple variations of an item, each with a different price.

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.

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.
