    Using RibbonGallery Control

    • 6 Comments
    The Ribbon Control is a pretty big control owing to the complexity of the Ribbon design guidelines. You can give it a try by downloading from LINK While there are several things to blog about, this post will focus on RibbonGallery. The download provides a sample that covers all features by implementing the Office Ribbon. This post will trim the sample to focus specifically on the RibbonGallery usage To whet our appetite, the dropdown of both the controls are RibbonGallery controls The gallery can be hosted in the following Ribbon Controls: § RibbonMenuButton § RibbonSplitButton § RibbonComboBox § RibbonMenuItem § RibbonSplitMenuItem § RibbonApplicationMenuItem § RibbonApplicationSplitMenuItem...

    3.5 features: Viewport2DVisual3D

    • 9 Comments
    Viewport2DVisual3D .... this new feature makes things a lot easier in the 3D world.. What this enables is putting interactive 2D on 3D. This makes things like having a textbox in 3D a breeze... < Viewport2DVisual3D x:Name = " vp2d_multiple_children " Geometry = " {StaticResource mesh} " > < Viewport2DVisual3D.Material > < DiffuseMaterial Viewport2DVisual3D.IsVisualHostMaterial = " True " Brush = " White " /> </ Viewport2DVisual3D.Material > <TextBox /> </ Viewport2DVisual3D > One other thing is mapping 3D points to 2D is so much more easier... Earlier on I had a post on mapping a mouseclick on a 3d model to a 2d coordinate. This involved using some barycentric coordinates and such....

    WPF Ribbon Basics

    • 15 Comments

    So you have Ribbon, Menu, RibbonTab, and then the Ribbon Group. When you create a new Ribbon application, you get this wireframe ready – so its easy to start.

    You got the group – lets populate it. If you look at the Xaml, the Ribbon controls have a SmallImageResource and a LargeImageResource property. This enables the ribbon to use the appropriate image when resizing. Each control can also have rich tooltips by setting the following properties

    Collapsing animation in WPF

    • 2 Comments
    its been some time since my last post.. so to get things going heres some simple animation code which collapses objects and the one above takes its place (something on the lines of tetrix :) ) .. the main part of this code is a small snippet which I came across some time ago (written by Bob Shogren) <EventTrigger RoutedEvent="Mouse.PreviewMouseDown"> <BeginStoryboard> <Storyboard> <DoubleAnimation Storyboard.TargetProperty = "Opacity" To = "0" BeginTime = "0:0:0" Duration = "0:0:2" /> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty = "Visibility "> <DiscreteObjectKeyFrame KeyTime="0:0:2" Value="{x:Static Visibility.Collapsed}" /> </ObjectAnimationUsingKeyFrames> </Storyboard> </BeginStoryboard>...

    New WPF Features: Binding to Dynamic Objects

    • 0 Comments
    This is part of a series on New WPF Features C# 4.0 allows creation of dynamic objects which is useful when you are interacting with dynamic languages. If you are unfamiliar with the dynamic concept take a quick look at this blog entry So back to WPF. We support binding to dynamic objects.. woohoo...

    3.5 Features: Enabled hyperlinks in RichTextBox

    • 3 Comments
    hmmm... that was one often requested feature. So to enable hyperlinks in RichTextBox all that is needed is to set the property IsDocumentEnabled on the RichTextBox. Type the following in XamlPadX and you have the hyperlink navigation working. < RichTextBox IsDocumentEnabled = " True " xmlns = ' http://schemas.microsoft.com/winfx/2006/xaml/presentation ' xmlns:x = ' http://schemas.microsoft.com/winfx/2006/xaml ' > < FlowDocument > < Paragraph > < Hyperlink NavigateUri = " http://club.live.com " > Live Games </ Hyperlink > </ Paragraph > </ FlowDocument > </ RichTextBox > A couple of things to notice here: 1> The Navigation is possible only on a Ctrl Click operation...

    sample 3D Xaml code

    • 2 Comments
    I was tweaking some sample xaml code (by AdamSmith) and the result was pretty kewl. So I thought it would be interesting to share it with the readers. The xaml code is attached. A nice extension would be to have a movie list at the bottom such that the selected movie plays... to play the movies you would need Media player 10 installed... I had media player 9 and it took me some searching time to figure that out :) .. EnJoi

    WPF: Adding speller to custom context menu

    • 2 Comments
    One of the interesting features in Editing is the speller and it works really well. :) One of the ineteresting scenarios when it comes to speller is to add the speller choices to a custom context menu. The speller choices would have to be added in the ContextMenuOpening event handler as below: spellingError = textBox.GetSpellingError(caretIndex); if (spellingError != null ) { foreach ( string str in spellingError.Suggestions) { MenuItem mi = new MenuItem(); mi.Header = str; mi.FontWeight = FontWeights.Bold; mi.Command = EditingCommands.CorrectSpellingError; mi.CommandParameter = str; mi.CommandTarget = textBox; textBox.ContextMenu.Items.Insert(cmdIndex, mi); cmdIndex++; } Separator separatorMenuItem1 = new Separator(); textBox.ContextMenu.Items...

    Sample form using listview

    • 2 Comments
    Recently I was clearing up my documents and I came across this sample I made. Thought it might be useful to someone out there and here it is. It’s basically something like a form but which dynamically grows as and when you fill up the rows. So the typical ‘Add New Row’ button is missing. J … Red (more like pink) rows indicate values being empty; green being obvious. :) .. Typically, you would be using a combobox instead of the textbox. It would result in a better perf experience. The code is simple using a listview which is bound to the data. This might look very familiar to Product Studio if you have used it ;) Code is attached Share this post

    WPF Touch Basics

    • 1 Comments
    In my previous posts, I briefly described the new WPF Touch feature. Was planning to get a more detailed post out but just couldnt get the time. Thankfully, Drake Campbell, one of our devs in Microsoft, sent me the following post on the basics of WPF Touch. Its a nice read.. So get started.... WPF Touch Basics Things to know before we start Understanding how RoutedEvents work might provide additional insight for this tutorial. http://msdn.microsoft.com/magazine/cc785480. What is Touch? Essentially it is your finger as the mouse. You can think of Touch as any action involving a single finger. Inertia effects, dragging and throwing something, are not included as part of Touch. Those are covered in Manipulations. Touch events include...

    Mapping mouseclick on 3DModel to a 2D texture coordinate

    • 1 Comments
    Some time back I posted a gadget with the rotating earth. This looked nice but it lacked some interaction. One of the things to make it interactive was to map the point of clicking to the texture applied on the globe. To get the 2D coordinate we need to perform a hittest on the Viewport3D and this will give us access to RayMeshGeometry3DHitTestResult object. This provides info on the mesh, geometrymodel, vertex indices of the triangle hit, and the barycentric coordinates . To obtain the coordinate we multiply the vertex weights (barycentric coordinates) with the cordinates of the triangle hit. We then scale this point with the texture size to get the actual pixel within the texture ( The link to the barycentric coordinates is a nice read and...

    12 handy things/tips to know about Vista

    • 7 Comments
    By now I hope that most of you have atleast tried Vista. If not, join the bandwagon . INSTALL VISTA!!! :) I love every bit of Vista and would like to share some handy tips and also bring into focus some apps that I use a lot. 1> Launch group favorites in IE : This feature is really nice. You can open all items in your Favorites group by clicking on the arrow 2> Shortcuts to quick launch items : We can use Windows key and number keys to launch the quick launch items. So win+1 would result in minimizing all apps 3> Snipping tool : This is a nice tool to get an image clip and to edit it. 4> Windows movie maker : I use this a lot to make movies of photos. You can add your own transitions and audio effects. This...

    WPF Balloon comments :)

    • 1 Comments
    Pavan has a nice post on creating baloon comments. The first thing that comes to mind on seeing the balloon comments is Comics. And guess what! thats exactly what I tried.. and presto You can get the original source code here . It overlooks positioning the arrows coming out of the comment boxes - this is a minor detail and I added a dependency property for this purpose. The update code is attached . As for the usage: < custom:BalloonDecorator Background = "Pink " PointerLength = " 30 " CornerRadius = " 5 " CornerPosition = " Right" .... /> Share this post

    WPF Blog Writer

    • 3 Comments
    Recently, I was trying my hand at creating a simple blog writer. The writer came out pretty nice. The app makes use of a base richEditor control (thanks to Praj ).. After a bit of tweaking it ended up like the above... So the app just makes a simple call in the xaml <custom:RichEditor/> ...tada ... you have it there!!! The next thing is to write to a blog... In this case, the writer is coded to post the entry on blogger, which makes use of the Google data API .. this could easily be changed for other blogs. It also makes use of a Xaml-HTML converter as the string passed needs to be in HTML. For now, its a blog writer - hence, it onluy writes. But it could easily be extended into a full blown Blog client. Do I hear anyone taking...
