asp.net 2/C#/VS2005
Using master pages
I have a page with several text boxes on it. I want to logically group
some of them. So I have a textbox that has required field and regular
expression validators for it. I also have a validation summary on the
page. For each of these four controls, I used the same value for the
"ValidationGrou p" property. I have also assigned header text for the
validation summary and error messages for the validators.
But when I run the page, don't enter anything into the text box, and
click an image button (to trigger a postback), nothing happens. No
error message shows.
Is there something else I need to do to make this work? 3 3492
for each postback control, you specify causesvalidatio n, and the
validation group if you want it to perform validation. this allows
different buttons to cause different validation or non.

Howdy,
I don't know why but it's by design (snippet from RegularExressio nValidator):
protected override bool EvaluateIsValid ()
{
string input = base.GetControl ValidationValue (base.ControlTo Validate);
if ((input == null) || (input.Trim().L ength == 0))
{
return true;
}
try
{
Match match = Regex.Match(inp ut, this.Validation Expression);
return ((match.Success && (match.Index == 0)) && (match.Length ==
input.Length));
}
catch
{
return true;
}
}
IMHO it looks like a big simplification (or 'screw up' would be more
convenient) from MST...

Howdy,
I actually missed one thing in the documentation:
"Note Validation succeeds if the input control is empty. If a value is
required for the associated input control, use a RequiredFieldVa lidator
control in addition to the RegularExpressi onValidator control. ". So you
have to add RequiredFieldVa lidator for the same control.
Regards

are no validation controls on the page there is no problem. But when the

I am having a slight problem that hopefully, someone can help me fix.
I have a form on a page. Many items on the form have validation controls

Also on this form are linkbuttons which must not cause validation. I have

Hi,
I have a DataGrid where in each row has couple of text boxes and an

Here is a question that needs to be revisited. I noticed that there are
more that a few posts about this in this group and in custom controls.
Here is the problem:
When inheriting from a webcontrol, say textbox for example, and
implementing the IValidator interface to make the control
self-validating, the control fails to participate in validation groups.
Using reflector, it is easy to see why; the page.validator casts all
the controls in...

How can I have a page with 2 different groups of controls (where each group
of controls contain textboxes, validation controls and a submit button) and
each group operate independently? for example, when the user clicks on the
first submit button, it wont submit unless all the controls in group 1 are
valid, likewise, when the user clicks on the 2nd submit button, it wont
submit unless all the controls in group 2 are valid.

What is currently happening is I have two validation groups (Billing,
