I have a function similar to this: private void ShowPage(Page page) { NavigationWindow mainWindow = Application.Current.MainWindow as NavigationWindow; mainWindow.Navigate(page); } This works great for browsing inside an existing window. I would like to open this new page in ...
I'm working on a simple application to start learning my way around WPF. I created a vector graphic in Microsoft Expression Design at 400px by 400px, mainly because I thought it would be easier to create it on a bigger canvas. I've exported the image to a XAML file as a series of objects within a 400px square canvas. All of the child ob...

If a line of text is wrapped to an additional line, how do I determine programmatically the point in the string where it was broken. Example: Input string = "This is a test of a wrapped line of text". Based on the width of the richTextBox it could display: This is a test of a wrapped line of text. What...
Is there a way to reuse a 3rd party control reference? For example, I have this referenced in my App.xaml xmlns:cust="clr-namespace:ThirdParty.Controls;assembly=ThirdParty.Controls" I don't want to repeat this 3rd party control xml namespace on each page/control that needs a control from the library.

On several of my usercontrols, I change the cursor by using this.Cursor = Cursors.Wait; when I click on something. Now I want to do the same thing on a WPF page on a button click. When I hover over my button, the cursor changes to a hand, but when I click it, it doesn't change to the wait cursor. I wonder if this has something to d...

In a XAML namespace declaration, is there a way to disambiguate differently named assemblies depending on your current configuration? I'm in the process of reworking a projects build system. The old system had the debug and release assemblies building to seperate directories, which meant the following (roughly) would work fine at the t...
I'm not sure how to approach this: I want a TreeView that will display some simple data from a hierarchical data structure. As a basic example (In XML, cause it's easy to type): <Node text="Root"> <Node text="Item 1"> <Node text="Item 1.1" /> </Node> <Node text="Item 2"/> </Node> The catch is that this could theore...
I'm having a problem with the WPF Tab View control that I was hoping someone here might be able to help me with. I want my tab view control to use rounded corners for the tab headers, because I think rounded tabs look better. To do this I modified the default control template for the tab by using the "Edit Copy" command in Expression B...

I am creating a custom WPF control that let's say for simplicity sake has a vertical stack panel with a "title" TextBlock, followed by a ContentPresenter. I want the font size for the "title" to be 5 Points LARGER than the size used in the content, which is inherited by whatever container the user places this control in. How can I speci...
