Event when "DataBindings" for are changed?

[Guest]

I have created a usercontrol in VS.NET 2003, and (at design-time only) I
would like to detect when the user changes any of the DataBindings for the
control. Basically I want my usercontrol to know information about the
datasource it is bound to, and at design-time this would be displayed to the
user as text on the usercontrol.

I have been unable to determine . The most likely candidate seemed to be
BindingContextChanged, but that doesn't fire when the user changes the
DataBindings.

Is there an event or override I can use in my usercontrol to detect this
property change?

For such design-time interaction you'll have to create a dedicated designer
based on ControlDesigner.

David,

You need to create a designer for your control. In the designer you can use
IComponentChangeService and subsciribe for ComponentChanging and/or
ComponentChanged events.
I'd suggest starting from the following article:
