New Integration example using RadControls for Silverlight
To demonstrate a real life business application that uses Telerik RadControls for Silverlight, we prepared another sample application showing a web portal about job offerings. We called it the JobBoard application. We managed to include there most of the currently available RadControls for Silverlight. These are: RadComboBox RadTreeView RadWindow RadUpload RadNumericUpDown RadDatePicker RadMediaPlayer The Home page features a "quick find" section at the top most part of the screen, a tree-view navigation on the left and a grid showing the results. The RadTreeView on the left loads its child nodes on demand for a better performance and faster initial loading. Clicking upon a grid-row pops a RadWindow containing... -

RadChart for WPF - What's next?
The feature list for the Q3 release of RadChart for WPF is already locked down, so we can start planning the releases after that. Customer feedback has always been paramount when making roadmap decisions in Telerik so here we are asking for your input. What would you like to see in the next versions of RadChart for WPF? Let me give you some hints if you are stuck: We could bring in more series types: -More rare financial charts like Kagi & Renko -Surface charts which represent real 3D data -Polar and Radar charts We could add more axis features: -Negative values -Strict mode (as in RadChart for... -

Don't store ASP.NET controls in Session, Application or Cache
In some cases you may end up with the following exception when working with RadControls for ASP.NET Ajax: "Script controls may not be registered after PreRender." The explanation of this error is simple - some UI control implementing the IScriptControl interface (e.g. any control from the RadControls for ASP.NET Ajax suite) is stored in the Session, Application or Cache and then is added in some live controls collection. Here is an... -

How To: Telerik RadGrid client-side caching with client-side binding to web services using LINQ to SQL
My new example illustrates how to cache the grid data client-side based on the current grid state. To do this we need to build a state key using current page index, page size, sort expressions and filter expressions: function getCacheKey(tableView) { return String.format("{0}{1}{2}{3}", tableView.get_currentPageIndex(), tableView.get_pageSize(), tableView.get_sortExpressions().toString(), tableView.get_filterExpressions().toDynamicLinq()); } Every time when we get new data we can store the result in our client-side cache: function updateGrid(result) { var stateKey = getCacheKey(tableView); if (!cache[stateKey]) { cache[stateKey] = result; } tableView.set_dataSource(result); tableView.dataBind(); } and when the next grid command occur we can call explicitly updateGrid() method if we have already saved result for the current grid... -

Sitefinity ad
Hello and thanks to everybody who gave their insightful comments in the first blog post by the Marketing Team. We have decided that it will be a good idea to blog more often, to engage in a conversation, and generally to shed some light on our work. We are aware that what we do is not directly related to programming but we hope that you may be interested in what else is happening at Telerik, besides lines of code being entered in VisualStudio :-) This post will continue where we left off last time. We would once more ask for your opinion on an ad we recently... -

Showing "tooltips" for the Nested RadGridView in RadMultiColumnComboBox
I promised that I will continue the "tooltips" series by demonstrating a "HOWTO" approach with our RadMultiColumnComboBox component. So what is the big difference with RadComboBox? What is really different is that RadGridView uses temporary elements to render grid cells, that are recycled every time you change something inside the screen estate of the RadGridView (say like scrolling). This means that setting the TooltipText properties of the cells in design time or through the API won't work. The solution That leaves us with the second approach only: to use the ToolTipTextNeeded event to get the job done. Here is a small example... -

Wrapping a .NET user control as an ActiveX
Before even asking why one should do anything like this, let me clarify that this is a good technique to spice up a bit your VB6 application. Now I know this is not cutting edge but still it is important to a lot of people (as I found out already). So let’s start then... Create a new solution that includes a Windows Forms application (to test easily the functionality provided by the user control). Then add a library project that will wrap our user control. What is demonstrated by this example is a very simple example that includes a label, and a...May 27, 2021 4 min read
