Web: ASP.NET AJAX

Hi everyone, As of Q1 2010 RadGrid will be equipped with a new filtering menu – a powerful and flexible feature the interest in which was sparked by RadGrid’s MVC counterpart offered by Telerik. It will be a sub-part of RadGrid's header context menu and will allow for filtering the grid's data on two conditions related with a logical AND operator: Perhaps, many of you are already eager to know how the new feature should be switched on/off. For this purpose a new property has been introduced into the RadGrid control -RadGrid.EnableHeaderContextFilterMenu/GridTableView.EnableHeaderContextFilterMenu. In addition, it is important that RadGrid.EnableHeaderContextMenu/ GridTableView.EnableHeaderContextMenu and RadGrid.AllowFilteringByColumn/GridTableView.AllowFilteringByColumn properties be...

Here is yet another handy column type coming for RadGrid. The GridRatingColumn will show a RadRating control for every data item in your RadGrid, both in view and edit mode. GridRatingColumn will support 2 modes of interaction. In the standard mode, GridRatingColumn will behave like an ordinary editable column. It will display a read-only RadRating control when the item is in view mode and an editable RadRating control when in edit mode. Alternatively, the rating column will allow you to change the rating value even in view mode. Thus, when RadGrid posts back, you can get the updated value on the server...

Have you ever thought of embedding a YouTube video in the context of a data-bound control? Recently, a client of ours asked for such a demo and this inspired me to create a code-library project that features this scenario and uses RadListView for ASP.NET AJAX as ‘videos host’. Depending on your goal, you can control the player via JavaScript code or you can just embed a static object. In the latter case you will need something like this: 1: <object width="425" height="344"> 2: <param name="movie" value="http://www.youtube.com/v/QT0e5XqNZdo&hl=en_US&fs=1&rel=0&color1=0x5d1719&color2=0xcd311b"></param> ...

If you really, really like the new and shiny extensions, you can use them in your WebForms application, too! Here are the needed steps: Add references to the following assemblies: System.Web.Abstractions System.Web.Routing System.Web.Mvc Telerik.Web.Mvc The first three are usually in the GAC. Copy the Content and Scripts folders from the extensions’ distribution into your project. The pages which will contain the MVC components will need to inherit System.Web.Mvc.ViewPage. Also, you should mock an MVC environment, like this: protected class ControllerMock : Controller { public ControllerMock(NameValueCollection queryString) { foreach (string param in queryString.Keys) ...

.csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } One very common issue that we’ve addressed in the Q3 release is the lack of a description field for the appointments. Until now you had to customize the advanced template in order to get one, but not any more. How to enable the integrated description field: Data Source - set DataDescriptionField to the corresponding column in your database: <telerik:RadScheduler runat="server" ID="RadScheduler1" DataSourceID="AppointmentsDataSource" DataKeyField="ID" DataSubjectField="Subject" DataDescriptionField="Description" DataStartField="Start" DataEndField="End" DataRecurrenceField="RecurrenceRule" DataRecurrenceParentKeyField="RecurrenceParentID"> ... </telerik:RadScheduler> Provider – set EnableDescriptionField to “true” and persist the Appointment.Description value in your provider. <telerik:RadScheduler runat="server" ID="RadScheduler1" ProviderName="XmlSchedulerProvider" EnableDescriptionField="true" > ... </telerik:RadScheduler> This is all you need for editing and storing the description, but what about showing it? A simple appointment template will do: <AppointmentTemplate> <div> <%#...
