validation strategy?

[Dabbler]

I need to insure that at least one of three phone number fields has a value
(requiredfield) but I'm not sure of a way to implement this without server
side logic. Is there a way to use the validation controls to do this?

Thanks.

[Nathan Sokalski]

I am not sure if there is a way to do that using the validation controls
other than using the CustomValidator Control. The CustomValidator Control
does require you to write server-side validation code, but if you write a
client-side JavaScript function as well you can set the
ClientValidatio nFunction property to allow JavaScript enabled browsers to
perform the validation client-side. I have never used this property myself,
but it doesn't sound like it should be too hard. Good Luck!

Clever workaround Phillip!

but I'm looking for a way to just insure that at least one of three
textboxes has a value in it without designating on as the mandatory field, as
these are in different sections of the form - e.g. work fields vs home fields.

I have a server side validation working now, but since it doesn't use
validation controls the error message doesn't disappear once the user tabs
out of the field.

I guess I'm going to have to brush up on my javascript!

Thanks for your suggestion.

Thanks Nathan, I think I will try the CustomValidator , I just need to brush
up on my javascript to access the values of the other controls.

There should be an intrinsic pattern to edit one control against multiple
other controls (MultiCompareVa lidator ?).

You can also have each of those textboxes copying their value to a hidden
textbox by handling the client-side event named "onchange", like this:

<asp:TextBox ID="txtHomePhon e" runat="server"
onchange="copyv alue();"></asp:TextBox>
<asp:TextBox ID="txtBusPhone " runat="server"
onchange="copyv alue();"></asp:TextBox>
<asp:TextBox ID="txtMobile" runat="server"
onchange="copyv alue();"></asp:TextBox>

At the end of your webform add a hidden textbox with validation controls
(for both required field and valid phone entry):

<asp:TextBox ID="txtPhone" Runat="server" CssClass="Hidde n"></asp:TextBox>
<asp:RequiredFi eldValidator ControlToValida te="txtPhone" Runat="server"
ErrorMessage="Y ou must enter at least one phone
number"></asp:RequiredFie ldValidator>
<asp:RegularExp ressionValidato r ControlToValida te ="txtPhone" Runat="server"
ErrorMessage="N ot a vaild phone nubmer"
Display="Dynami c"
ValidationExpre ssion="^\(?\d{3 }\)?\s?\d{3}[-\s]?\d{4}$"></asp:RegularExpr essionValidator >

Then in the javascript script section of your code:
function copyvalue()
{
var txtSrc = window.event.sr cElement;
var txtTarget = document.getEle mentById ("txtPhone") ;
if (txtTarget!=nul l)
{
txtTarget.value =txtSrc.value;
}
}

Of course make sure your stylesheet has the .hidden style defined, e.g.
..Hidden {display:none;}

Even more clever!

The only fault I see in this is that I can't mark the missing fields
visually, right now I use validators to put exclamation point gif next to
missing fields and error text in a validation summary. so for the time being
I'm not using a validator but rejecting the page if server side method
determines all phone fields are blank and setting visible label fields with
image and error text.

Now I'm thinking it would be cool if I could perform the tests server side,
then trigger validation controls from server code, so the validation errors
would appear in the validation summary.

Sorry, guess I'm want it just so ;)

Thanks for a classy suggestion though, I might wind up having to reduce
expectations and use it ;)

The custom server control that you will build has to have a strategy to
validate the entries using javascript. This is what we are doing here. In
other words, this discussion is not irrelevant. You can package the
javascript skills that you might learn from this discussion into your custom
validator's client-side script and add to it the portion that you already
developed (server-side validation).

As for the *only fault* that you identified (can't mark the missing fields
visually), I modified the code slightly to do that and placed it as a demo on
this link:
http://www.webswapp.com/codesamples/...box/demo2.aspx

Are you sure you clicked on the right tab for the source code? There are 2

Even more clever!

The only fault I see in this is that I can't mark the missing fields
visually, right now I use validators to put exclamation point gif next to
missing fields and error text in a validation summary. so for the time being
I'm not using a validator but rejecting the page if server side method
determines all phone fields are blank and setting visible label fields with
image and error text.

Now I'm thinking it would be cool if I could perform the tests server side,
then trigger validation controls from server code, so the validation errors
would appear in the validation summary.

Sorry, guess I'm want it just so ;)

Thanks for a classy suggestion though, I might wind up having to reduce
expectations and use it ;)
