Automatic operations with RadGrid and SqlDataSource control
Although many of you are probably familiar with this project from the code library section on our site, I thought it is worth the effort to demonstrate once again in public how easily (with literally zero lines of code) you can configure RadGrid to perform automatic data-editing operations and refresh the data in the database directly. The video I have prepared for this purpose is available in this section on our site, below is the direct link: http://www.telerik.com/ClientsFiles/product.videos/32/ On a side note, for Martin and all the others who had problems with the screen size of the Excel-like filtering video posted before, I am pleased to... -

Shortcut on Silverlight 1.1
Here at Telerik we are constantly working with the new cutting edge technologies. As Silverlight 1.1 alpha hit the road we were keen to research all the new things we can do with this new technology ... But there was one little problem - the lack of help and documentation. Our experience with WPF help us a lot to get into the new technology, but Silverlight is a new platform and it has its differences from WPF. So when we were contacted by the O'Reilly to write a book for Silverlight 1.1 we decided that this will be a very good opportunity...October 17, 2007 2 min read -

Localizing RadEditor Prometheus by Using Global Resource Files
The Localization of the new RadEditor "Prometheus" now works with resource files and not with XML files as before. This change was made as resources represent the standard ASP.NET 2.0 mechanism for doing this with extensive built-in support in Visual Studio. As a result, it is a much easier approach for the developer in creating or changing a localization. Another major advantage of this is it is also much easier to deploy and maintain. The following movie, available at http://www.telerik.com/ClientsFiles/product.videos/30/, provides guidance how to make your own localizations by using global resource files. More information is also available in the following forum sticky note: Localizing RadEditor by Using Global Resource... -

On dynamically creating server controls
Every once in a while I see code which looks like that:public class MyCustomControl : WebControl{ protected override void Render(HtmlTextWriter output) { SomeControl someControl = new SomeControl (); someControl.ID = "SomeID"; someControl.SomeProperty = "SomeValue"; someControl.RenderControl(output); }}There are two problems with this code: The child control is instantiated in the Render methodFrom control execution lifecycle’s point of view it is too late to instantiate controls in the Render method. Even if you add them in the controls collection some features won’t work just because it’s too late – postbacks, viewstate to name a few. The child control is never added to the controls collection. This means... -

How wrong custom ViewState handling may harm more than help
As some of us have found last Friday this article in MSDN about how to store your ViewState in Session is totally wrong. Using the Reflector you can find very easily that ControlState will be erased if you access more than once PageStatePersister. The correct implementation should be: PageStatePersister _pers; protected override PageStatePersister PageStatePersister { get { if (_pers == null) _pers = new SessionPageStatePersister(this); return _pers; } } How about overriding SavePageStateToPersistenceMedium / LoadPageStateFromPersistenceMedium? If you do this you should update your PageStatePersister or you will miss the ControlState once again. Example: protected override object LoadPageStateFromPersistenceMedium() { object state = THESTATE; if (state is Pair) { Pair statePair = (Pair)state; PageStatePersister.ControlState =... -

RadControls for WinForms last minute controls
RadControls for WinForms Q2 is live! It has been exhaustive, but motivating 4 months since the last major release and I am very happy to announce the new version of our innovative Windows Forms components. As I had promised the last time, I will be providing you with interesting and helpful information about the WinForms suite. With Q2 out of the door, I will turn to two of the basic controls which we have included in this release, literally at the last moment, namely RadBreadCrumb and RadDateTimePicker. RadBreadCrumb is a navigation control directly related to the well-known to the community RadTreeView for... -

How To: Format RadGrid PDFs
On Monday, I showed you some the new settings in RadGrid 5 the enable you to control certain aspects exported PDFs. We looked at how you can easily set the PDF's metadata, change its filename, and even control the PDF's security settings. All of these settings- along with the ability to force the PDF to open in a new window- can be set with a single property in the Grid's new ExportSettings configuration block. What we didn't look at on Monday is how you can control the formatting of your exported PDFs. Today we'll take a look at how you can customize... -

The new default skin (and how to switch back :)
With the Q2 release, we have decided it is time to refresh the look and feel of RadControls components to stay on the edge of the latest trends in visual design for the web. And ever since Vista, black is the new white… so we just had to join in with a trendy new theme for the default skins of our controls. The Q2 2007 skin sports a modern black twist, improved contrast, and larger font-sizes/more generous white space for a touch of web2.0 in your applications. While we ardently urge everyone to switch to the new look, we do...
