    Building BI Dashboards with Telerik RadControls for Silverlight and WPF Webinar Follow-up

    Despite the initial audio and connectivity issues, the Building BI Dashboards with RadControls for Silverlight and WPF Webinar proceeded well and we got to dive into some of the issues people face in these scenarios as well as how RadControls for Silverlight and RadControls for WPF can help answer those challenges.  This is very close to the presentation that I gave this past weekend at the New England BI Code Camp, except the webinar is a little more focused on Telerik controls.  :) In this presentation, we look at a fictional requirements list for a customer would look like and why Silverlight or WPF can...

    Displaying live streaming data with RadGridView for Silverlight and WPF

    Animated cells on value changes   When dealing with streaming data which is updated over time the end user should be able to quickly track changes at a glance. A typical application that would benefit from this would be a financial dashboard, live data monitoring and tracking systems etc. For the purpose of illustration I have prepared a small simulation of streaming financial data (stock prices) .     In my previous blogpost I have already demonstrated how we can alter/extend the behavior of cells in RadGridView by placing a user control inside. This blog post demonstrates a more real-life and business oriented scenario. All...

    How - to: Automatically re-order, re-sort and re-group RadGridView (Silverlight and WPF) on change of the underlying DataSource.

    RadGridView for Silverlight and WPF supports sorting, grouping, filtering and editing. However, if a column is sorted for example and edited afterwards, we expect the newly-edited item to find its way in the sorted GridView. But it does not, unless “coded” to do that. So, what we want to achieve is to make the Grid aware of the changes thus enabling it to organize its elements correctly, corresponding to the requirements of the user.  Therefore, the expected behavior of the application will be the following: In order to achieve the desired result, we need to take the following steps: 1. Create Business Object There...

    Styling RadChart for WPF and Silverlight gets easier

    It’s been awhile since the Q1 SP1 2010 release, but let me introduce you to a couple of new approaches to styling, which we added and failed to openly manifest. First, there is the ability to build your own palette of brushes, that will be applied to the RadChart: <telerik:RadChart x:Name="radChart1"> <telerik:RadChart.PaletteBrushes> <SolidColorBrush Color="Magenta" /> <LinearGradientBrush StartPoint="0,0" EndPoint="0.75,1"> <GradientStop Color="Red" Offset="0" /> <GradientStop Color="BlueViolet" Offset="0.5" /> <GradientStop Color="#af000000" Offset="1" /> </LinearGradientBrush> </telerik:RadChart.PaletteBrushes> </telerik:RadChart> .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; }   Here is the result:   Using images is as...

    TreeView in ComboBox with RadControls for Silverlight or WPF, final take

    It seems that there are many developers that want to use this combo, as my previous blog posts are quite popular. The problem with the suggested solution is that you need to customize the control template of RadComboBox. There is a much easier way to put a RadTreeView in a Popup – by using a RadDropDownButton: <telerik:RadDropDownButton HorizontalContentAlignment="Left" DropDownWidth="200" IsOpen="{Binding SelectedItem, Converter={StaticResource ObjectToFalseConverter}, ElementName=TreeView, Mode=TwoWay}" Content="{Binding SelectedItem.Text, FallbackValue='Please, select an item.', ElementName=TreeView}"> <telerik:RadDropDownButton.DropDownContent> <telerik:RadTreeView x:Name="TreeView" ItemsSource="{StaticResource Items}" ItemTemplate="{StaticResource ItemTemplate}" /> </telerik:RadDropDownButton.DropDownContent> </telerik:RadDropDownButton> .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; }   This way you could easily access the RadTreeView instance in the code-behind, however I would recommend using a ViewModel and bindings instead.   The DropDownButton Content property is bound to the SelectedItem property of...
