How can validator code get the FormView data object

Hi;

We have a FormView tied to an ObjectDataSource. How can our C# code for a
CustomValidator get the data object of the data in all the fields?

Hello Dave,

As for your custom validator , would you provide some detailed info on its
code logic? For example, what target controls will it validate and what's
the data required for its validation. Generally, a validator control will
be assoicated with another single control for validation. And for FormView
or other template databound control, if you want to valiate any sub
controls in the control template, you should put the validators in the
certain template.

Please feel free to let me know if there is anything I missed here.

Sincerely,

Steven Cheng

It validates all the controls. This is how we are working around the problem
of each validator taking up space with their hidden text - instead we have a
single custom validator that checks everything.

Thanks for the reply Dave,

Thus, you may need to manually use script to explore the client-side script
of the FormView control. You may first locate the super element of FormView
through clientID and then locate its child elements. For such scenario,
you'd better first review the generated client-side html of the formview
and then determine how to author the script to explore the client-side
element hierarchy.

Hi;

What is the recomended way to handle validation.

If I put a validator on each control (2 validators in some cases) when they
do not show their hidden text makes the form look weird because of the
spacing they cause.

If I use a single CustomValidator then I have to go query each control for
it's value which is a pain.

Hi Dave,

In my opinion, using separate validators is better. The validator is
inheriting from Label, which uses html element SPAN. Would you please tell
me more about the page layout, such as why the hidden SPAN will cause
layout problem.

I am guessing it is how IE displays it but we have cases like:

<TextBox> <RequiredFieldValidator> <RegularExpressionValidator> and what
happens is if the textbox has data but it does not match the regexpr, then
after the text box there is a long space (the hidden error message for
RequiredFieldValidator and then the rrror message for
RegularExpressionValidator - and that looks very very wrong.

Also, if neither message is displayed, the spacing still occurs which pushes
the position of subsequent controls down.

Hi Dave,

Validators have a property called Display which could control the generated
SPAN's style. I believe setting to Dynamic or None should work for your
purpose:

Let me know the result.
