Hi.

I am trying to validate a textbox using custom validator. If a specific radio button is checked and the textbox is empty, I want to display error. I used a custom validator with control-to-validate set to the textbox. In the server function, I check if radio button is checked and textbox is blank, set args.isvalid to false. However, when I trace it, the function is never hit. I have checked the properties and they are set properly (causes validation ,,,)

Any idea what might be wrong?

protected void CustomValidator1_ServerValidate(object source, ServerValidateEventArgs args) {

args.IsValid = false;

else

Thanks,

Hi,

You have to call this.CustomValidator1.Validate() to fire the event.

Cheers,

Thanks for the reply Robin. I had already done that and it didn't work. When I trace it, after clicking the button the is supposed to trigger the validation, it stops at this.CustomValidator1.Validate(), I try to step into it but it skips it and goes to the next line. The button that is clicked does fire up other validations, it is just this one validation that doesn't get fired.

Anyone?

1. Set the ValidateEmptyText property to true on the CustomValidator. Otherwise, it never evaluates a blank textbox.

2. Make sure your button's Click event tests Page.IsValid is true before using or saving the data.

3. Make sure the button's validation group name matches the group name on the Validator.
