What I don't understand is: how do I perpetuate the object? do I have to create a singleton? in the click event, how do I access the "object that is being edited" eventu...
Trying to determine if it is possible to bind the SelectedValue of a ComboBox to the inputs of multiple ObjectDataProviders with XAMAL Bindings.

Everything is going along fine with my binding of the different controls using Eval("ColumnName") until I get to the price column. My goa...

I have a TextBox that is bound to a Text-property on an Entity-object. I'd like to be able to re-format the text the user enters in some circumstances - e.g. if the user enters "2/4" (a fraction) - I'd like to change that to "1/2".
