I have a web form that has several asp.net validation controls on it. I have one textbox that is using a function to validate the textbox contents against a SQL server database. I have the coding complete but I want to use a validator control to indicate if the textbox contents passed or failed so that it becomes part of the page validation along with the other validation controls on the form.
I tried setting the customvalidator.isvalid = false but it does not see to work.
How can I do this?
