View 3 RepliesDoes 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.

Apr 6, 2010Can any one let me know "How to validate the length of the text present in the textboxes of a Gridview using javascript".
For Example: In a page I am displaying a Gridview with textboxes inside it and a button on the page. The user need to input some text in the textboxes of the gridview and click on "Submit" button. When the user clicks on Submit Button, we need to validate the length of the text present in the textboxes of the gridview. If the length of the text inside the textbox of the gridview is less than 10 , we need to throw an error message. In the same way we need to do validation for each and every textbox inside the gridview.

View 3 RepliesJavascript - 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?

How 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.
