I have been part of Telerik’s Silverlight team for almost a year now, and I too well know that our marketing team is just two floors away to say anything bad about marketing.  So I will just say that now having Silverlight 2 in its official version out, marketing mix should adopt one more P in its four P’s concept, Ptechnology. That is why, I will try to explain this topic step by step, so that all marketing guys attracted by the name of this topic can delete the first paragraph and give it to their development teams for consideration....

When asking the user to provide input in any application it can help to give them guidance on what you are expecting.  There are a variety of ways to accomplish this, but one in particular seems to be very effective.  If you have ever used Microsoft PowerPoint you will undoubtedly have seen a screen similar to the graphic below.

The instructional prompt effectively conveys to the user where to type a title and subtitle for the slide.  Better yet, the user can ignore these prompts and proceed with other activities in the application.  Live Search Map provides another example of...

I’ve run into this error before and last night it reared its ugly head again. You’ll find it from time to time when switching to Design View in Visual Studio to work with custom server controls. The bug is in Service Pack 1 of VS and can be quite annoying.

 

It has been submitted to Microsoft and they claim to be working on a solution which will “fix it in subsequent releases” of Visual Studio. Unfortunately, developers (like me) don’t want their productivity to suffer while we all wait for a fix from Microsoft. So here are a couple of steps...

We started a survey to gain your mostly valuable feedback on your experience and expectations with the Silverlight platform and the controls we provide. Your involvement will be much appreciated and you will be awarded 1000 Telerik points for taking the survey. We want to direct our future Silverlight development into building the critical and most important blocks for your existing or future Silverlight applications.

Greetings everyone,

With the brand new look-and-feel of telerik.com we introduced for the landmark Q3 2008 release you probably noticed that the support resources searching capabilities have changed, too. Our aim was to expose intuitive and straight-forward means to browse the available resources based on their type and find the information/examples you need in a blink of an eye. In a nutshell, we would like each visitor to have the ability to search by product line and get a list of results with a leading indicator image designating the resource type (demo, help topic, knowledge base article, code library project, etc.).

Very often you need to parse/convert TextBox Text property value to some other type however I’ve never seen any universal approach for this so far… and I’m offering you one :)

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI.WebControls;

public static class TextBoxExtensions
{
    public static T Value<T>(this TextBox textBox)
    {
        return (!String.IsNullOrEmpty(textBox.Text))? ChangeType<T>(textBox.Text) : default(T);
    }

    public static T ChangeType<T>(object value)
    {
        return (T)Convert.ChangeType(value, Nullable.GetUnderlyingType(typeof(T)) ?? typeof(T));
    }
}

It's simple, isn't it? :)...

Deep linking is an unique feature of RadNavigation allowing you to use page navigation by simply changing the URL in the browser address bar. Now you can provide a link directly to every page from your application.

In order to use deep linking in page navigation scenario you have to make sure that any changes in the state the page is reflected to the browser’s address (bookmark). To do this you have two...

Today I would like to highlight one of the newest controls added to the WPF / Silverlight control suites in November – the RadGauge control.

RadGauge combines its rich assortment of radial, linear and numeric gauge types with very flexible layout composition abilities thus allowing you to attain a new level of data visualization quickly and easily.

Let us discuss the basics of the layout composition and how it is implemented in the gauge control.

There are three levels of controls that participate in the layout:

• RadGauge
• LinearGauge / RadialGauge
• LinearScale / RadialScale / NumericScale

 

RadGauge is the top level class but as far as the control...
