Multiview and Validation

[Chuck P]

I am using a Multiview control and some validators.
The multiview is being used in a homegrown tab control
Click on a tab it display one of the views.

I have a submit button that I would like to validate all of the
controls in all of the views within the multivew.

I am guessing their is no way this going to happen on the client,
since the controls on the non-displayed views are not available to the
DOM/javascript?

However, on page postback if I do page.validate, page.isValid. I
don't believe the controls in the other views are being tested. How
can I validate all the controls within the multiview?

Hi Chuck,

It's a design decision that controls/validators in a hidden View will not
be validated; also you're right about the client-side validation: the
controls inside hidden View aren't rendered to client at all, thus not
possible to validate them at client-side.

As a workaround, I'm afraid you will have to manually make each View active
then do the validation again:

private void ValidateMultiView(MultiView mv)
{
int savedIndex = mv.ActiveViewIndex;
for (int i = 0; i < mv.Views.Count; i++)
{
mv.ActiveViewIndex = i;
Page.Validate();
}
mv.ActiveViewIndex = savedIndex;
}


Note: if you have code in the MultiView's event ActiveViewChanged, please
be aware that above code will trigger the event too; you might want to use
a member variable to bypass the logic there if it's caused by this function.
