    ASP.NET Validation and so much more

    Perhaps some of you know that Telerik's tools provide great interoperability with the Professional Validation And More ("VAM") package by Peter Blum. Peter has a great set of products that offer much more than the validation controls that come with VS. As part of our collaboration, Peter was kind enough to give us a free license for internal use. It was sitting in our software repository and catching dust up until last week. We had to tackle an issue with validation groups in the back-end application of www.telerik.com - the postback triggered the wrong form on the page which wasn't supposed to...

    Importance of meaningful error messages

    The other day I had a very strange Visual Studio 2005 experience. I was testing the new design time capabilities of r.a.d.tabstrip and something went extremely wrong. My test environment consists of a WebControlLibrary project (the control itself) and a WebSite with a single aspx page containing nothing but a humble r.a.d.tabstrip. The site has a project reference to the web control library so it gets rebuilt whenever I build the site. So far so good. Here is the fun part - whenever I rebuilt the site and refreshed the page I received the following error:Ok, i said to myself, it's debugging time. I...

    The (TextBox) loss of text conspiracy

    While working on AJAX support for r.a.d.calendar, one of our relatively new controls, I came across a very interesting issue with the ASP.NET TextBox control. The problem was related to ViewState management, or better said, the absence of such. The TextBox simply didn’t seem to handle any ViewState information and the TextBox values were not persisted and reloaded correctly after PostBack. What I was doing wasn’t rocket science - I wanted to make the TextBox (System.Web.UI.WebControls.TextBox) persist its value when the user scrolls forward or backward through the month views. My first thought was that I’m brain-dead and have had...

    No more Internet Explorer for Mac

    One of the people on our design team sent us the good news this morning - it's official that Internet Explorer for Mac will no longer be supported and will not be available for download as of December 31st, 2005. You can read the full bulletin at the Mactopia site:http://www.microsoft.com/mac/products/internetexplorer/internetexplorer.aspx?pid=internetexplorerI am sure there won't be a lot of tears in the eyes of our development team now that the "villain" will be finally gone. We will not stop to support Mac IE immediately but we do plan to drop support for the notorious browser at some point in Q1 2006. We do recommend to customers...

    Test-driving Windows shell scripts with Windows Scripting Host

    I was creating a small banner rotation script yesterday.  It needed to be tiny, lightweight and easy to deploy, so I chose to do it in JScript as it is available on every Windows machine.  I usually do small automation projects in Ruby, but the machine that has to run the script does not have Ruby installed.  I am a closure freak, so I went for JScript (VBScript does not have closures).The script has to select a random subfolder from the source location and copy all its files to the destination.  I don't have much experience with Windows Scripting Host's (WSH)...
