CustomValidator ValidateEmptyText

[Trebor100]

Afternoon all,

I'm hoping that someone can save me from drink tonight by helping out on this one.

I have a CustomValidator as follows:

<asp:CustomValidator ID="customVal_1" runat="server" ValidateEmptyText="true" ControlToValidate="textBox" ClientValidationFunction="doStuff" OnServerValidate="servLocation" CssClass="validationError" ErrorMessage="error msg."></asp:CustomValidator>

The ClientValidatonFunction "doStuff" isn't fired when the the text box is empty. Any thoughts / workrounds? I'm in the tricky position of needing bespoke validation and as such requiredFieldValidators are not an option. I thought this problem had been fixed on .net 2.0 but I guess not!

For info the doStuff presently just presents an alert which I know is functioning fine.

Thanks for any help.

Rob

You need to post more code(dostuff) and explian what you are tying to validate

 

[Trebor100]

function doStuff(sender, args)
{
alert("moooo");
}

doStuff will ultimatley do alot. It will be checking a series of other fields to determine if this field becomes mandatory. I'd ideally like to do this without postbacks turning controls on / off etc. The validation aspect will be easy enough as long as I can get the event to fire if the field is empty.

Cheers,
Rob

this is a common scenario, "conditionally required" fields. An alternative to elaborate and/or complex validation is a change in how the options are presented to the user. If you created the UI to flow more like a wizard (not the wizard control, just a set of directed questions) then you can direct the user where to go and request only the information that's required. then it's just a series of simple inputs and required field validators.

I just created a page and used your HTML. It worked for me. There must be something else in your code causing the problem.
