Global Cancel

[Joe]

I want to create a single Cancel method to cancel all changes made to any
fields in a UserControl. I have a method that creates a Binding object, adds
it to a collection and than adds the Binding to the control.

textBox1.DataBindings.Add(CreateDataBinding("Text", myobject, "Caption") );

public void Cancel()
{
foreach (Binding b in this.Bindings)
b.BindingManagerBase.CancelCurrentEdit(); // This never changes the
value back
}

Is there anyway to create something like I want?

Thanks,
Joe

Joe,

Working with data and Net means for the developer working with datasources
and for the end-user with the controls. Mostly the datasource is a
datatable.

That one has a method.

I hope this helps,

Thanks but this doesn't help because the dataSource is not a DataTable.

The object you are binding to has to support being able to undo changes.
This does not come for free.

Your object has to implement the IEditableObject interface, I suggest you
look at that.

Joe,

What is than the datasource?

Thanks. I'll look into it.

BTW - some of the objects are booleans and strings.
