Hi,

I have some code which searches my controls to see if any data has been entered. If no code has been entered, I want to inform the user of this using a validation summary control that I have. I am struggling to work out how to pass an error message to the validation summary as a custom validation needs (as far as I know) to have an entry in the controlToValidate property.

Anyone have any tips?

Another way to put it could be how do I validate multiple controls using the custom validation control?
