    Passing parameters to a UserControl inside RadWindow for Silverlight

    I just wrote a simple application that demonstrates how to databind a treeview to a dummy data source and edit its items in a UserControl, placed in a RadWindow. You could see my other blog posts for examples with web service binding and upgrade the application to suit your needs. To accomplish the requirements, we need to add a property that will contain the edited data item on the UserControl. When the selection in the TreeView changes, we will update that property with the new selection and then open the RadWindow. The UserControl will create a copy of the data item...

    How do I pause execution in JavaScript?

    The current article is taken from javascript.faqts Contributors: ha mo, Daniel LaLiberte, Brent Boyer, Martin Honnen, mercury rising,   There is no true wait, sleep, or similar function in either the core JavaScript language or in client side JavaScript. Client side JavaScript however provides     setTimeout('js code here', delayInMilliseconds) which allows you to schedule execution of piece of script and setInterval('js code here', intervalInMilliseconds) which allows you to periodically execute a piece of script. So if you wanted (pseudo code) statement1;  wait (someDelay);  statement2;  you would stuff the code into functions: function statement1 () {      // your code here  }  function statement2 () {      // your code here  }    and call statement1();  setTimeout('statement2()', someDelay);      If you wanted (pseudo...

    Auto-complete ComboBox with WCF Service and RadControls for Silverlight

    Sometimes we need to load very large amount of items in a ComboBox and let the user select one of them. Usually in those cases the ComboBox allows typing in order to auto-select the items, that contain the text in the control. Such scenarios are possible with RadComboBox for Silverlight and now I will show you a simple application, that demonstrates what I think is a better practice for the implementation. We want to put all words from the English dictionary of RadSpell for ASP.NET in a RadComboBox for Silverlight and allow the user to select one of them, that will...

    TreeView in a ComboBox dropdown using RadControls for Silverlight

    As far as I can tell from the experience of my colleagues with RadControls for ASP.NET AJAX, one of the common feature requests for RadComboBox and RadTreeView is combining them into one piece. Recently we started to receive similar requests for RadComboBox and RadTreeView for Silverlight. Placing a TreeView in a ComboBox sometimes makes a lot of sense, so I decided to research the best way to do it.   The first, the simplest and most obvious way is to place a RadTreeView as content of RadComboBox: <input:RadComboBox> <nav:RadTreeView  ItemTemplate="{StaticResource ItemTemplate}"  ItemsSource="{StaticResource ItemsSource}" /></input:RadComboBox> This works, but it has one important limitation: RadComboBox cannot...

    RadControls for Silverlight Demo with ADO.NET Data Services

    Yesterday I wrote about how to databind RadTreeView for Silverlight to ADO.NET Data Service and use Load on Demand. The simple application from yesterday was upgraded to a small back-end application for the Northwind database, that allows editing and deleting products. This time I decided to give it to one of our designers and our new Silverlight front end developer and they implemented this slick design: The application is available online: http://demos.telerik.com/silverlight/northwindbackend/Default.aspx The source code can be downloaded from here: NorthwindBackend.zip In addition to yesterday's application, NorthwindBackend has extended data source, that provides simple undo mechanism and ability to update and delete products...
