It's been about three years since I did anything meaningful in the ...

In Asp.Net Combobox, there is a useful property, AppendDataBoundItems, that causes whatever items are bound to the control to be actually appended to whatever "statically" added ad design time.

Hi there, I've been working with Bea's solution here for a while and finding it very helpful. Problem now I'm having is when I drag-n-drop items within or to another ListView control and I want to scroll up/down "during" the drag (moving an item from index 30 to index 1), it's not happening. I would have to drag to the top of the visua...

I have a form in my application that uses a binding source to bind the controls to a model object. This works, and handles basic validation such as ensuring that the user doesn't enter text into a numeric field, for example. I am using an ErrorProvider, and setting its datasource = the binding source in order to display the error messag...
