Javascript - Hidden Validator Controls Still Validate?
Dec 28, 2010I've set up a page that uses JavaScript to hide or show rows in an HTML table, depending on the state of a checkbox.
So far, so good. But this is a data entry form and some rows include validation controls. However, it appears that if I hide a row (using JavaScript: style.display = 'none') that contains a validation control, the control still validates on an attempt to postback.
way I can do this but have the validation controls not do anything if that row is hidden?

View 1 RepliesHow To Validate The Length Of A Textarea Using A Regular Expression Validator
May 19, 2010I'm looking to validate the length of a textarea using a regular expression validator. It should allow all characters and crlfs. I'm also concerned about crlfs counting as 1 or 2 characters, I'm concerned it may be different across browsers but I'm hoping ASP.NET regulates it. Also, I'm saving to a mix of varchar and nvarchar fields in MSSQL, do I need to be concerned about the way crlfs are saved there? I'm in a hurry to do this right, so I'll be researching all this on my own but I'm just hoping someone out there might have experience handling such concerns.

Web Forms :: Is Using Both A Required Field Validator And A Compare Validator
Mar 1, 2010When it comes to field validation, when I use a Compare Validator to make sure a date is a date or a numeric field has a number, I must also use a Required Field Validator to make sure there is something actually enetered. In other words, the Compare Validator allows a blank value even though a blank is not a date or number or whatever.
Is using both a Required Field Validator and a Compare Validator the way to do this or is there some way to make the Compare Validator also require input of some kind?
Does A Custom Validator Have To Be Used With The Validator Callout Extender
Jul 6, 2010I have a validator callout extender that works, it shows the callout box. But, it does a postback. It didn't do a post back the first time I clicked the button but it did for subsequent times. I read on the AJAX site that a custom validator must be used with this for it to work. I'm currently using this with a required field and regular expression validator. It works, the callout appears, but it doesn't work every time with out the post back.I posted this to see if there is a way to get this to work with a required field and regular expression validator, with out using a custom validator. I'm using the newest release of the toolkit, so I thought the documentation may be old, since the callout is appearing.
