Unrecognized Tag Prefix or Device Filter ‘asp’

B01I0001 One of the companies I work for recently took over a project from another vendor.  As we started to maintain the site, we noticed that we could not drag and drop controls onto the page and get any more than a stub of  the control. <asp:hyperlink runat=”server”></hyperlink> is ALL we got when we dropped the hyperlink control onto the designer.

In fact, every ASPX control on the page displayed the error, “Unrecognized tag prefix or device filter ‘asp.’”

What’s up with that?

Thinking that there must be something wrong with our development environment, or at least something wrong with how we have the project configured, I started my search on Google.

Test Sending Email without a Server in ASP.NET

back-041 By now, most people are familiar with the fact that ASP.NET will send mail from the codebehind by simply adding a few lines to your web.config file and adding another few lines of code in the codebehind file.

ASP.NET Web Design Software

Artisteer - Web Design GeneratorWhat if there was a product that would allow you to create your web site themes as easy as you could create a PowerPoint presentation theme?  Wouldn’t that be cool?

This past weekend I discovered just such a product.  At first, I was pretty skeptical.  I mean, I normally pay $50.00 or so per theme when I put up a DotNetNuke site and here is a product that will let me create very nice themes that I can use in BOTH my ASP.NET based sites AND my WordPress based sites for just over 3 times that price.

Multi-Step Processing in ASP.NET

B01I0045

I received the following question a few days ago but I’ve been so busy with billable work that I just haven’t had a chance to answer it until now.  Actually, I’m still busy, but I hate letting these questions go for too long.

“Right now I am working on a project where I have to screen a user.  This is a multi-step process.  At the end of the process I store the data back to the system. Currently, I am storing all the options a user will select in a session variable and then finally using them at the last step. Can you please suggest a better way to store this temporary data that does not require using a session? This type of situation comes up a lot.  We’ve used multiview to get it working. But this does not seem to be viable in all situations.”
