ValidationSummary breaks validation?

[da]

I've inherited an ASP.net 2.0 (VB.net) application that uses a lot of
GridViews and DetailsViews.

I've ran into an odd issue with validation. We've added some validators to
the INSERT template to validate a field. They include a required field
validator, a Regex validator checking the length of the field, and a custom
validator.

Each is then assigned to the same validation group. We then added a
validationSumma ry referencing that same group.

Here's the problem:

If we assign the ValidationGroup to the validators, they stop validating. If
w remove the ValidationGroup property, they then work just fine.

3 of us have looked at this and we can't figure out what would be causing
this. Any theories as to what is going on?

Did you set the ValidationGroup property of the Button (or whatever is
causing the postback) as well?

I am not sure what the expected behavior should be if the Button does not
specify a ValidationGroup and but all validators do. Should the Button
cause validation across all groups or no validation at all?

Re: ValidationSumma ry breaks validation?

a button with no validation group, will only call validators with no
validation group.

No! That could be it.

It's actually a EDITITEM template in a DETAILSVIEW control. The postback is
being caused by the rendered INSERT link within the control itself.

Ah! thanks for the hints! I think we've found what we were missing. Here's
an example of what we had to add:

Protected Sub dvActivityType_ ItemInserting(B yVal sender As Object, ByVal e
As System.Web.UI.W ebControls.Deta ilsViewInsertEv entArgs) Handles
dvActivityType. ItemInserting
' upon inserting item, we need to validate the group of fields in
our view/template
Page.Validate(" valActivityType ")
' if they are not valid cancel the event
If Not Page.IsValid Then
e.Cancel = True
End If
End Sub

The controls that cause the poastback (say the textboxes and/or the submit
button) need to have the validation group set as well...
