> Hi Giorgio,
>
> Based on my understanding, you have a VS2005 WinForm application project
> in
> which a form has some controls on it. You select one control on the form
> and go to the (DataBindings) entry in the Properties window. When you
> click
> the drop down arrow in a sub entry under the (DataBindings), you get a
> null
> reference exception. If I'm off base, please feel free to let me know.
>
> To make things clear, I'd like to ask you some questions:
>
> 1. Could you tell me what the control is you're binding, a TextBox,
> ComboBox or something else?
> 2. Does this problem exist on other controls?
> 3. Is there any custom data source in the project?
>
> I look forward to your reply.
