On the forums I saw this interesting problem where there was a need to round the corners of a stackpanel inside a border with cornerradius set... The top is what you get and the bottom image is what you want. The simplest thing to do here is to set the padding on the border so that the stackpanel doesnt bleed around the corners. But when that doesnt meet your requirements you will need to set the clip property on the child in the OnRender function so that you get the correct clipping. The code for

I got a couple of queries from the readers asking if I could provide a slightly non-trivial sample of using automation. So I created a split button user control which looks something like this If there are no items then you get a checkable button. The items are created in a popup and are generated on demand. This makes the automation a bit interesting. As you can see the control supports 3 patterns – · Invoke (for the button) · ExpandCollapse (for the drop down) · Toggle (for the checkable option)

Earlier on I had written an app, BlogPadm which was fulltrust and the writer used Google Data API to write the content to Blogger.com. However, when you create an xbap version of it, a problem arises in that you cannot make WebRequests outside site of origin and hence, the xbap version of the above failed to take off. The workaround is to create a webservice at the site of origin so that the calls are forwarded. However, the focus of this app was to test cookies. So I hosted a blog server and had

A month ago, I was browsing through different blogs and came across Denis Vuyka's blog post on connecting objects on the canvas... Nice post... Being an avid fan of mind maps, that was the natural extension to the library that he created. Check it out There are 3 types of objects which are basically the same... they contain rich content... Right clicking on the objects opens up an editable Richtextbox... In case you paste in Links, you can click them (Ctrl + Click) ... This opens the link in a new

I recently came across a Hyperbolic tree implementation on codeplex using WPF and thought that a nice usage of it could be in writing a mind map creating application.... I tweaked some of the original code and got a tree with editable nodes... Its been laying around for sometime, so I thought it best to put it out there so that you folks can continue its development. Though its not functional in the true sense, it does provide the basic functionality like saving and opening (albeit to the same file)...

Now thats what I call WOW ... For .NET developers this is like getting hold of the holy grail :) ... " We'll begin by offering the source code (with source file comments included) for the .NET Base Class Libraries (System, System.IO, System.Collections, System.Configuration, System.Threading, System.Net, System.Security, System.Runtime, System.Text, etc), ASP.NET (System.Web), Windows Forms (System.Windows.Forms), ADO.NET (System.Data), XML (System.Xml), and WPF (System.Windows). We'll then be adding

One question that often pops up among WPF app developers is UI testing... WPF enables this scenario through a new accessibility framework.

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

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

So 3.5 beta2 is out and it has quite a lot of features. So one of them is the filtering mechanism for IME languages. This was not a problem in the english and other non-IME languages. The problems were the events associated with IME input - TextInputStart/Update/input... A major concern was that it was not possible to determine where the composition took place. Now all these issues have been fixed and filtering in these languages is a breeze. I came up with a sample calculator with the filtered IME
