Data bound textbox is not updating

Do you ever get that annoying problem where you have bound your business object to some controls on a Windows Form and yet after you make a change to the data in a control, your change is not moved to the underlying data source?I had that happen today, but only when I had made the change through code and then clicked on the Okay button immediately after.

To see how all of these options work, I have updated the example from the previous chapter to show you all of them: As you can see, each of the three textboxes now uses a different Update Source Trigger.

The first one is set to Explicit, which basically means that the source won't be updated unless you manually do it.

This behavior is controlled by a property on the binding called Update Source Trigger.

It defaults to the value "Default", which basically means that the source is updated based on the property that you bind to.

using namespace System; using namespace System:: Collections:: Generic; using namespace System:: Component Model; using namespace System:: Data; using namespace System:: Drawing; using namespace System:: Text; using namespace System:: Xml; using namespace System:: Windows:: Forms; using namespace System:: IO; namespace System_Windows_Forms_Update Binding int main() Imports System Imports System.
