View 2 RepliesI have the following problem...
I'm developing an an asp.net 2 application in c#. This site is being built with accessibility in mind, and as such I need a to build a registration from that validates using server side scripts and
not use client side validation.I need to validate a textbox (whether any text has been entered), if a check box has been checked.
Bear in mind that I can't use any clientside code such as javascript postback that is wired into the <asp:CheckBox /> control.
I have a textbox that I am "custom" validating to lookup in a table to see if the name exists. When I test it out, if it finds a duplicate, the validation results in an error message as I would expect. First is this only works if I add autopostback to my textbox and that I click elsewhere on the page. The other issue is that after I type a string in my textbox, I want it to validate such that if it returns an error, I don't want to submit the form until the validation is good.
How would I programatically set this up?

What I would like to do is use a CustomValidator on the user name textbox to check if the user name entered already exists in the database. I've read about the possibility of using the ServerValidate event for the CustomValidator control but I can't figure out how to make a connection to the database, query it to check the existing user names, and then fire off the CustomValidator if the user name exists.
