RequiredValidat or not working

[tshad]

I have the following:

<asp:textbox id="ProfileName " columns="45" runat="server" />
<asp:RequiredFi eldValidator
ControlToValida te="ProfileName "
Display="Dynami c"
Text="Name Required"
runat="server" />

I also have an imagebutton that goes to a routine to save a record

<asp:ImageButto n ID="SaveRecord " runat="server" Visible="true"
OnClick="Modify Record_Click" ImageUrl="../../buttons/SaveChanges_0.g if" />

I put nothing in the ProfileName field and it still goes to the function
ModifyRecord_Cl ick instead of displaying the "Name Required" message.

Why is it not working?

Thanks,

Tom

I have a similar problem and wonder if this is like mine.

Are you having this problem in both IE and Firefox browsers ?
Are you prepopulating the field for the user to show the current value from
a datastore ?

Actually,

It does it with both.

But I also was getting an error before in the function the button was
calling, so I assume the validator wasn't being called.

I assumed that because I got the error, the validator didn't work.

What is happening is that the function is being called after the Validator
has run?

I thought if there was an error, the function wouldn't be called. Am I
wrong here?

Thanks,

You're right, the function should not be called if the page is not valid

since it fails in both browsers, and you aren't prefilling the form, I would
need to see your code for "ModifyRecord_C lick" to determine of the problem
is there.

Actually, what I did to make it work is:

Sub ModifyRecord_Cl ick(sendor as Object, e as ImageClickEvent Args)

if not Page.isValid then
exit Sub
End If

I guessed the function does get called, so I just added that code to solve
the problem.

Now the problem is in my other routine, which is called by my LinkButton
(the Modify routine was called by an ImageButton).

The code is the same:

Sub DeleteProfile_C lick(sender as Object, e as EventArgs)
trace.warn("ins ide SelectProfile")

if not Page.isValid then
exit Sub
End If

But when I do it I get the error:

Page.IsValid cannot be called before validation has taken place. It should
be queried in the event handler for a control with CausesValidatio n=True or
after a call to Page.Validate.

So in the Modify function, the validate function is being called and in the
Delete function it is not ???????

The method Page.Validate() is called automatically by each of Microsoft's
submit controls (Button, ImageButton, and LinkButton) unless you set
CausesValidatio n to false. If its not called, you cannot use Page.IsValid as
you've found.

The submit controls call it in their OnClick method (which then fires your
Click event handler). It runs after Page_Load.
- Make sure CausesValidatio n=true or you call Page.Validate() before calling
Page.IsValid
- Don't call any of this from within Page_Load. Let it happen in the post
back event methods.
- If you are using CausesValidatio n=false because you don't want to validate
every validator, call individual validator's Validate() methods. Then check
the IsValid property on those individual validators.
- This is all server side code. It should not be affected by the browser
type.
- It is possible that if javascript is not working, your Click post back
event will not run. This happens when your submit control calls
__doPostBack() on the client-side to set itself up for server side
processing. Without javascript running, __doPostBack() never runs.
