I've recently been using Excel and Powerpoint 2007, and it's seems clear that the shapes are using WPF. Edit - I know the shapes have existed in Office for ever, that is not my question. Look at the fill possibilites for shapes in 2007, look at that gradient fill, look at its parameters - that's the same as WPF as far I as I can see. S...

Hello all, I'm developing a large line of business app with C# and WPF. Our standard is to include accelerator keys for buttons on all forms (Save, Cancel, Search, etc.). I've recently noticed that when a form is loaded, the accelerator key is active even when the user does not press the "Alt" key. For example, our Search button uses...
I have in my application a data template that has a few buttons. I want those buttons' even handler to be fired in the current page (I am using this template in many pages) rather than in the Application.xaml.vb/cs file, since I want different actions on each page. I hope I am clear. ...

How would one do this in WPF? ...

Hi there, I'm struggling with a binding that only works when declared inside a Window's resources area. As soon as I move the declaration to a UserControl's resources area, the binding fails. No error message, but the value is not updated when the value of the slider (source) is changed. I would like to use the storyboard inside one of ...
I'm dynamically building a WPF FlowDocument from a datasource. One of the data elements is a fragment of HTML - I need to figure out a way to parse that and insert it into my FlowDocument. I've found HTMLToXAMLConverter which will return a XAML representation of the HTML, but I'm still not sure how to best go about instantiating that X...
