I'm working with ASP.NET 3.5. I have a list box that users must add items to (I've written the code for this). My requirement is that at least one item must be added to the listbox or they cannot submit the form. I have several other validators on the page and they all write to a ValidationSummary control. I would like this listbox valid...

Is it even possible to perform address (physical, not e-mail) validation? It seems like the sheer number of address formats, even in the US alone, would make this a fairly difficult task. On the other hand, it seems like a task that would be necessary for several business requirements. ...
I need to validate this simple pick list: <select name="<%= key %>"> <option value="ETC" SELECTED>Select an option...</option> <option value="ONE">Lorem ipsum</option> <option value="TWO">dolor sit amet</option> </select> So the user would never submit the form with the, excuse the repetition, "Select an option..." option ...
Hi We are using the standard method for our controls to report broken BO rules. This is done via the interface IDataError in our BO’s and in XAML the control is bound to the BO’s property etc. This approach works OK. But we need to show 2 types of visuals in the UI depending on the type (or category if you like) of the invalidation erro...

Hi, I have a ASP.NET 2.0 webpage with 2 UserControls (.ascx). Each UserControl contains a bunch of validators.

I currently have a fairly robust server-side validation system in place, but I'm looking for some feedback to make sure I've covered all angles.

Hi, I'm investigating an annotation-based approach to validating Spring beans using spring modules.
