Multiple Validation Controls

[barrylowe]

I have a text box on my form which is used to enter a reference number. It has 2 validation controls attached to it. The first is a standard required validator, the second is a custom validator which runs a little bit of code that checks to see if the reference that has been entered already exists.

The controls sit side by side on my form in the following order:

Textbox RequiredValidator CustomValidator

Both validators work fine, the problem is that if it is the Custom validator that is triggered, then there is a gap between the text box and the validation error message where the unseen required validator is hiding.

Can anyone help?

A quick fix would be to get rid of the RequiredValidator and build that logic into your custom validator! Otherwise, you may have to use javascript/CSS to position the elements based on whether they are shown or not.

I tried doing that but the code in the custom validator does not fire unless a value has been entered in the text box which kind of defeats the purpose.

Change the ValidateEmptyText property of the custom validator to True

I can't seem find that property of the validator control. I am running framework v.1.1, is that property part of v.2.0?

Yes, that has just been introduced in version 2.0:

Is there any workaround for this in 1.1?

 

[ca8msm]

Yes (see my first post). You could either use the CustomValidator and add a client-side function to check for a empty value or you could use the second suggestion I offerered.
