Reset all bindings?

[zachattack05]

I have 7 different bindingsources on a form right now and I have a "cancel" button to allow a user to reject the changes they made and revert back to the original data in the dataset.

Instead of having my cancel button click event call something like:

private void buttonCancelChanges_Click(object sender, EventArgs e)
        {
            dS_DataSet.RejectChanges();
            BindingSource1.ResetBindings(true);
            BindingSource2.ResetBindings(true);
            BindingSource3.ResetBindings(true);
            BindingSource4.ResetBindings(true);
            BindingSource5.ResetBindings(true);
            BindingSource6.ResetBindings(true);
            BindingSource7.ResetBindings(true);

            ToggleEditMode();
        }

can I just loop through all of the existing binding sources on the form? I can't figure out how to do that if you can.

Any suggestions, or is this really the only way to do it?

Instead of using the designer for these binding sources, you can create a list of them programatically, then foreach the list to reset the bindings.

Alternatively, you could do something like:

foreach (BindingSource bs in this.components.Components.OfType<BindingSource>())
                bs.ResetBindings(true);

If you are worried about performance, I wouldn't use this too much. Especially if there are a lot of components in your form, since the filtering to find only the binding sources might take a while.

Thanks!

I think I'll stick with what I'm doing now instead, it's not worth a performance hit.

Using a List<BindingSource> would leave no performance hit.

Oooooh! Excellent idea! I like it! I don't know why I didn't think of that!

Thanks!
