    Glassy buttons, interrupted?

    Has the time come to challenge the top place of glassy look in today’s web notion for haute couture? What could possibly act cooler than a glassy button on your web site? Admit it, even if you never had it, at one point or another you secretly craved for one. One of those fat, professional looking glassy buttons that scream out loud style & grace and are said to sky-rocket click through rates. Everyone’s got it - for the last couple of years, web interface has been all about this glassy feel – ironically enough, with the fall of the...

    Adding controls to Visual Studio Toolbox

    The Problem As Rumen said, adding controls to Visual Studio toolbox can be a tedious procedure. That's why r.a.d.controls are automatically added in the toolbox during installation. This makes it easier for the developer to start using them. However there is a catch - no control is added in Visual Studio 2005... Our toolbox adding code runs without an error but ... nothing happens. Several months ago I found the following forum thread which basically said that the code used to add toolbox items in Visual Studio 2003 will simply not work in Visual Studio 2005. And it is 100% right! We decided to abandon this...

    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...
