Javascript - Hidden Validator Controls Still Validate?
Dec 28, 2010
I'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?
I'm learning asp.net page life cycle. I find an article on MSDN [URL] It says that If the request is a postback, control event handlers are called. After that, the Validate method of all validator controls is called, which sets the IsValid property of individual validator controls and of the page. And the picture in the article also says validate fires after event handling. If this is true how can I get status of validator when I handling the event?
I am using required field validator for controls.In one scenario iam not showing one textbox so when I click on button validation is firing so I can I do this to not fire validation when the textbox is in hide?
this hidden input is used by a star rating control. the user gives a star rating of 1 to 10 by clicking on the stars and some javascript detects which star was clicked and fills the input with the corresponding number.
I want to use a RequiredFieldValidator to ensure that the client has selected a star and if not return an error message to my validation summary.but the validator seems to be throwing an exception. How do I do this?
Dispite what the topic subject says, I really want the opposite. I panel with a form and validations that's hidden. I also have another form that I'm trying to use on the same page, but the page won't validate because of that hidden form. Is there any way around this? Can you tell the brower NOT to validate just those hidden fields?
I am running the code below in a .net 2.0 content page.There are no containers such as wizard etc. When I click on the submission button for debugging purposes I get 'Nothing'. why I can't access the 'controlToValidate'?

I'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.
I would like to validate the textbox for specific text and it must not be blank. But the regular expression validator is not validating if the text box is BLANK. However, it validates if I type something in the text box.
How can I make regular expression to trigger even if the text box is empty?
Should I use Required Validator + Regex Validator at the same time?
I have a form that contains several textboxes and each one paired with a required validator. Each box reads a value from a dataset, and on submit click, update the database with the new value. For some reason, one of the validator always returns the error message even if I enter a value in the textbox. My code is something like this.
I'm using this code to access controls inside a gridview using javascript:

Thing is that for some reason it doesn't locate Validators. If i add the line - alert(sid) , it will show me all the Id's of the controls inside the GridView except for validators.

Is it possible to have "Required Field Validator" controls to validate more than one field (example I have 12 textboxes that are required. I want to try an avoid having 12 RFV controls. If a validation does get triggered, is there a way to display a customized message ("textA is empty" or "textB is empty") etc.?
I have a validator on a textbox that validates against a list to ensure that the user doesn't input the same name. When testing it, if I type in the same name including the same case structure, it returns an error. If I change one letter to a different case, it doesn't return an error but rather my SQL server returns a duplicate error. How do I change the server-side validator so that it picks up duplicate names regardless of case?
