Skin Exchange Program
I am enthusiastic to announce the launch of the Telerik Skin Exchange Program – http://www.telerik.com/skins! We have created a meeting place for community members to exchange home-grown skins for the Telerik ASP.NET AJAX components. We know a lot of you have come up with amazing designs for our components and wanted to enable a platform to show these off and help the community. Seeing the tremendous support you guys give to each other every day on our forums and code library, I am confident you will take up on the initiative so we can build up a useful new resource... -

Using ValueConverter to edit Slider's TickTemplate
RadSlider for Silverlight has a neat functionality that allows you to display tick marks along the track. But what if you are not pleased with the current design of the ticks? Of course you can completely change the look of a tick mark. Let’s say that instead of bluish rectangles, you want your ticks to be ellipses, or triangles maybe. This is easily achieved by setting the TickTemplate property. <telerik:RadSlider TickPlacement="BottomRight" TickFrequency="1" Maximum="10"> <telerik:RadSlider.TickTemplate> <DataTemplate> <Grid> ... -

Adding Mouse Wheel support in Silverlight. The easy way.
One of the best uses of our Routed Event extension is implementing missing system events in Silverlight, such as MouseWheel and RightButtonUp/Down. The API we provide is the same as WPF, so when Silverlight eventually gets support for those events, most probably you will not have to change much. Other good thing is that you do not need to write any JavaScript, or to know what's going on beneath. The bad thing is that you will have to enable the windowless mode of the Silverlight plug-in, which will slightly decrease the performance of your application. To attach a Routed Event handler for the MouseWheel event on a... -

Performance tip: Using sprites with navigational RadControls
As a strong believer in sprites, I was inspired from a question that came up in a forum thread earlier this week, namely: how to use sprites in a RadTreeView? Well, I think it's rather limiting to write only about the RadTreeView, so this post discusses the technique for all of the navigational RadControls. You can download the sample page and give it at try. Most of the code is quite straightforward - simply setting the CssClass property and a few layout adjustments. Please note, however, that this CSS is tightly bound to the skin that is currently used, so changing skins might not work... -

RadControls and ASP.NET Ajax 4.0 Preview
Two days ago Bertrand Le Roy announced the first preview of ASP.NET Ajax 4.0. If you haven't read its roadmap you can check it out here. Lots of cool stuff is coming out - client-side templates, bindings, fluent client-side API (similar to jQuery) and more. Things are a bit hectic here because of the Q2 2008 release. Nevertheless Vlad and I managed to prepare two demo pages demonstrating how to use the client-side templates introduced in the ASP.NET Ajax preview with RadGrid and RadTreeView (yes it was that easy). Both controls are bound to web services and the client-side templates are used to visually customize the... -

Browser Inconsistencies with Scrolling and Padding
The other day I was researching a slight RadGrid header and data cell misalignment when using scrolling with static headers. Finally, it turned out that there is a breaking change in the way Firefox 3 treat scrollable elements with an applied padding style. To be more specific, this browser version does not include the padding zone into the scrollable area, and as a result, the inner area of the element becomes smaller. Safari 2 and 3 behave the same way. Here is a very simple testing scenario: <div style="width:400px"> <div style="width:100px;padding-right:300px;background:orange;overflow:auto"> <div style="width:500px;height:100px;background:yellow"> </div> </div> </div> The above HTML code will be displayed by Firefox 3, Firefox 2, IE7, Opera 9 and Safari... -

Disabling Full Row Selection in Vista Explorer
One of the things that irritates me the most in Vista is the enabled by default Full Row Selection in Explorer. To see what I'm talking about open an Explorer window in Details View and try to select files with dragging a rectangle. I googled a bit and found that there is a solution for the problem: Under the key: [HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced] Create a new REG_DWORD value named FullRowSelect. Leave it's data as 0x0 and you are set. After some more digging, I found several scripts which will automatically set and unset this key for you: Keith Miller' Windows Stuff I hope this helps....May 27, 2021 1 min read -

Visual Studio Tip: Creating and Consuming an Item Template
These days there are a lot of cool ways for .NET developers to be more productive. From code generation to refactoring, there is never a shortage of plug-ins out there to help us in this goal. But let's not forget about the great tools and features already built into Visual Studio that we can use. One feature I have started using recently is the item template. Whether you know what an item template is or not, you use them in your every day development. Item templates are those pre-written files you add to your project whenever you need a new ASP.NET...May 27, 2021 4 min read -

Web Resources demystified: Part 3 (Troubleshooting)
In this post I will show you how to troubleshoot Web Resource related problems and how to deal with them. If you are using an ASP.NET server control with rich client-side behavior it is likely built to utilize web resources. Sometimes your page loads and that rich server side control does not work at all - the tree view does not expand, the grid cannot sort etc. Most of the times this is because the JavaScript files of those controls have failed to load. If your browser is configured to prompt on JavaScript errors you may see the following error messages: "RadTreeView...
