Another popular feature in RadGrid for ASP.NET AJAX is header context menu and I’ve made small demo how to achieve the same in RadGridView for Silverlight:   Similar to the custom filter row you can enable this functionality for your grid with a single property: <telerikGrid:RadGridView x:Name="RadGridView1" telerikGridViewHeaderMenu:GridViewHeaderMenu.IsEnabled="True" telerik:StyleManager.Theme="Vista" /> Enjoy!

I recently posted an entry regarding the Radial Gauge for WPF where I demonstrated how you can create a half circle gauge.  Not long after that post, I received a question asking about Linear Gauges and how to use multiple scales in a single Linear Gauge.  It is not that there is a functional difference, but rather a visual difference.  The Office Black theme (shown below) has a border area in the middle where the linear gauges were overlapping causing a visual collision.  There are a number of ways that you can accomplish a task and I think one of...

With all the new features we have introduced in our latest release you might have missed some of the improvements we have implemented in the framework for ASP.NET Online Demos. These are the most important changes that will improve the experience of browsing through the demos: New Search: You can now quickly search the titles of all demos (They are now about 700!)   Change Skin: There is a new option to change skins in the demos. You can easily see how the demos will look if you set another skin. The change skin dropdown is implemented ...

To enable RadContextMenu for every grid data row you should do: 1) Handle RowLoaded event for the grid and create RadContextMenu: void RadGridView1_RowLoaded(object sender, RowLoadedEventArgs e) { if (!(e.Row is GridViewHeaderRow) && !(e.Row is GridViewNewRow)) { RadContextMenu rowContextMenu = new RadContextMenu(); // create menu StyleManager.SetTheme(rowContextMenu, StyleManager.GetTheme(RadGridView1)); // set menu Theme // create menu items rowContextMenu.Items.Add(new RadMenuItem() { Header = "Show row ID property value" }); ...

Say you've assigned a resource to an appointment and you want to make it visually distinctive from the rest.  The resource can be anything - room, status, priority and so on. Until the Q1'09 release this required writing some code, but not any more. You can now define a set of resource filters that will apply a CSS class when a match is found. For example: <telerik:RadScheduler runat="server" ID="RadScheduler1" ...> <ResourceStyles> <telerik:ResourceStyleMapping Type="Calendar" Text="Development" ApplyCssClass="rsCategoryGreen" /> <telerik:ResourceStyleMapping Type="Calendar" Text="Marketing" ApplyCssClass="rsCategoryRed" /> <telerik:ResourceStyleMapping Type="Calendar" Text="Work" ApplyCssClass="rsCategoryOrange" /> </ResourceStyles></telerik:RadScheduler> .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; } You can match resource's type, key and/or text. All matching rules will be applied. For your convenience, we've included a number of predefined styles: rsCategoryBlue...

As you know RadControls for ASP.NET AJAX controls fully leverage .NET 3.5 and come with built-in support for LINQ, LinqToSQL, EntityDataSource, ADO.NET DataServices, and WCF Web Service. With Q1 2009 our online examples feature .NET 3.5 examples for all databound controls (Grid, Scheduler, ComboBox, Menu, TreeView, PanelBar). In this post I will guide you through the process of creating a RadComboBox which loads its items on demand using WCF services. This will be a step by step tutorial, but if you are familiar with the process you can jump directly to the online demo. The steps below show how to load the items of RadComboBox...

I’ve made another demo (similar to this one) on how to save and restore various RadGridView settings using IsolatedStorageFile and DataContractSerializer. Again to turn on this for your grid you can simply set RadGridViewSettings.IsEnabled attached property: <UserControl x:Class="SaveLoadSettingsWithRadGridViewForSilverlight.Page"    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"    xmlns:telerik="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView"     xmlns:ts="clr-namespace:Telerik.Settings">     <Gridx:Name="LayoutRoot"Background="White">         <telerik:RadGridView ts:RadGridViewSettings.IsEnabled="True" x:Name="RadGridView1" />     </Grid> </UserControl> ...

If you are planning to use the RadRibbonBar and want to get started quickly, then you might consider using the RadRibbonForm template in VIsual Studio.  While you can use a standard form the RadRibbonForm allows you to use the RadRibbonBar and have it extend into the Title bar, just like Microsoft Office.  You will first need to install the template so it is available to you in Visual Studio.  To get started, navigate to the C:\Program Files\Telerik\RadControls for WinForms [version]\Templates.  If you are using CSharp open the CSharp directory, there are Visual Basic versions as well, in appropriately named folders,...

Since our RadGrid for ASP.NET AJAX filter row is very popular, I’ve made small demo how to achieve the same in RadGridView for Silverlight:   To turn on this for your grid you can simply set GridViewFilterRow.IsEnabled attached property: <UserControl x:Class="CustomFilterRow.Page" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:telerikGridViewFilter="clr-namespace:Telerik.Windows.Controls.GridView.Filter" xmlns:telerik="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView"> <Grid x:Name="LayoutRoot" Background="White"> <telerik:RadGridView x:Name="RadGridView1" AutoGenerateColumns="False" telerikGridViewFilter:GridViewFilterRow.IsEnabled="True"> <telerik:RadGridView.Columns> ...

Recently a question regarding how to change the BackColor of the RadMenu for WinForms.  I thought it might be easier to outline this process with screenshots so I put together a quick post to answer the question. After creating a new WinForms application project, I added a RadMenu.  The screenshot below shows that the default color of the menu is blue. The quickest way to accomplish this task is to click on the SmartTag in the DesignView.  Then select the Edit UI Element menu option. This will open a new window which is called the Element hierarchy editor. Within the Element hierarchy editor, select the...
