I figured it out by using a CollectionViewSource and then filter method into a code routine that filters the enumerator. Still love your website and visit as often as I can.

Great article, I have an enumerator list that is bound to a combo box using the ObjectDataProvider works great, the problem is I need to be able to keep different elements of the enumerator from showing in the combo box based on other settings in the application. Using your example above; in most cases I want all three values but for this one instance I want just Small and Large (not medium) from the TShirtSizes enumeration (in short I need to keep the enumeration for the combo box because data is persisted to stream as an enumerated value). Any help would be appreciated.

Thanks

Yes, I realize that this sample is quite limited when it comes to language translation. I have seen people implementing this scenario by adding attributes over each value in the enumeration with better descriptions of each value. This method is more realistic than the one in this post because it allows sentences to be displayed in the ComboBox, but I’m not sure how this would tie into globalization. You’re probably aware of the globalization docs in MSDN. Other than that, our WPF globalization expert, Chris Han, maintains a blog here. He’s incredibly smart and knowledgeable on this topic, and may be able to give you some pointers.

Sorry if I can’t be more helpful on that topic,

Charles Petzold had an usable example for me how to do it, and it works lovely!

Thanks a lot, I owe you one!

I believe a MultiBinding would solve your problem. Basically, it allows you to bind to two sources at the same time. You will have to write a converter that takes both sources as a parameter and produces the final value you want to show in the target.

I will keep this in mind for a future blog post. In the meantime, I’m pretty sure the SDK has samples with this. If it doesn’t I’ll make this my *next* blog post. Let me know.

I want to draw my own fancy border around a TextBox.
Problem is, it can’t be scaled automagically like a rectangle could, I need to bind to the size of the textbox to use it as coordinates in a path.

With a custom converter this does work nicely for ActualWidth or ActualHeight alone, but of course to get the bottom right corner I need to bind to ActualHeight and ActualWidth at once, and I can’t find no way to achieve this.

Is there a way to bind to ActualWidth and ActualHeight at once? Or to create a converter that is bound to both and can itself be bound to?

Or maybe there is a whole other way to get the size of a control in a template for userdrawn content that can be bound to?

Thanks a lot!
