Here's my hypothetical example. I have a very simple WPF window with a one Button. The Button.Click event has a handler that goes like this. Action doit = () => { Action error = () => { throw new InvalidOperationException("test"); }; try { this.Dispatcher.Invoke(error, DispatcherPriority.Normal); } catch (Exception ...
(I know there's some close duplicates out there, but none of them were able to help me, please hear me out) I have the setters of my model throwing appropriate exceptions when something attempts to set an invalid value. This works wonders for validation when the user types a new value. However, when I create a new model object, the ini...

If you bind to a view-model property that is a nullable double (or int) how do you allow a user to specify nothing. I'm looked into validation but I can't see how I could get that to help. It seems like if a textbox is blanked out WPF sees it as an empty string and then doesn't put the into the vm proptery. So 2 ways around it I ca...
I'm attempting to setup a MenuItem that will have a submenu of page numbers that can be selected. I want to bind the ItemsSource to a list of page numbers (actually to the PageCount with a converter creating the list) and then bind the IsChecked property of each MenuItem in the sub-menu to the PageIndex. My problem is with the second b...

Hi, I'm applying a TextDecoration to a TextRange in a RichTextBox. Works fine except that if the user types at the end of the range, then the decoration is continued. Eg. if the word "am" is decorated in "I am here" and the user changes "am" to "am not", then all of "am not" will be decorated. I just want "am" to be decorated. Any ...
Hi All, Im looking into how to make an effect on my WPF 4.0 application where I have a listbox that can switch from list view (i.e. a vertical stack of my own items) to a grid view (tiled list from left to right) via an animation (not a jump to and from). I have been looking into Fluid Layout in Blend 4, and messing around with it, but...

I mean they are implemented as static but still applies to all objects. Second point of con...
