Web Forms :: Compare Two Dates In "dd Mmm Yyyy" Format In Compare Validator
Apr 17, 2010
I am trying to check for a condition such that a date in an input control (textbox) is not greater from a date 1 years from current date(exactly) and also it should not be less than a date 1 year back from current date. for eg. if today's date is "21/dec/1990" then usen cannot enter a date in textbox which is less than 21/dec/89 and it should not be greater than 21/dec/1991. for this i first tried to confirm the greater than condition, i wrote the following code:
When attempting to place controls in different content areas using Masterpages and trying to use a compare validator, I get the error: Unable to find control id 'txtStartDate' referenced by the 'ControlToCompare' property of 'cvlDate'. I have also attempted to set it within the c# code behind in page load: cvlDate.ControlToCompare = txtStartDate.ID and by using findControl there must be an easy way to achieve this?
I have an AJAX Calendar extender that puts the date in the textbox in this format: MMMM d, yyyy. I also have a compare validator control that does at DataTypeCheck for DATE. However, when the Calendar Extender enters the date as MMMM d, yyyy (eg. November 2, 2010) the compare validator doesn't like it. It only seems to like the date in the format MM/dd/yy. Not sure how to get this compare validator to accept the input format from the calendar extender?
When 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?
I'm trying to compare two dates to make sure one is not greater than the other using a customvalidator and validatorcallout. However, I can't seem to get it to work and I've tried many examples but I can't seem to get what I want to work
I have two textbox as naming : txtInitiateDt and txtDisposalDt.
When user give 2nd textbox value from datepicker it should chk whether the given value shouldn't more than to date and also less that 1st textbox value.
I did it & also works good...bt there's an error arise when i host the site on client machine where only framework and database is present.
And the error is "String Value is not in correct dateformat" and fr this exception other events are blocked.
All of the examples I can find show the compare validator being used to see if two values are the same. Validation is succesfull if these values are the same, such as password confirmation.I want validation to succeed if values are not the same. I want to use this to be sure that someone doesn't enter the same value for two phone number fields. I want the two values to be different. Can the compare validator be used for this? I wasn't able to find any properties or examples that used it in this way. If not, how should this be done?
I have compare validators that I build on the fly in code behind that validate textboxes that are also built up in the code behind:
[Code]....
These work fine until a postback occurs. After a postback they still validate the form (i.e. they don't let you postback) but the error message won't display.
I am facing an issue which is i have Custom Validator on TextBox control and Compare Validator on the Same TextBox control now the issue is if custom validator and compare validator is firing at the same time. My Scenario like this I am checking the Date in DD/MM/YYYY format in Custom Validator and the entered should not be greater than Todays date i am checking in Compare Validator so if my Custom Validator fails then it should not fire Compare Validator but its firing how can i Synchronize my above functionality.
I've got a booking form which allows users to pick dates. User clicks FromDate button which activates calendar control, they select date from calendar which then populates a textBox. I have a compare validator which checks that the SelectedDate is greater than the current date, if the SelectedDate is in the past then the validator fires error message. This works as fine, however, when the validator fires it disables the FromDate button so the user is unable to pick another date from the calendar as the focus goes to the TextBox which is being validated - how do I get around this? Here's the code:
I have a requirement where i want compare only the date part of a DateTime Object not the seconds with the another object.I tried if(DateTime.Compare(dt1, dt2) == 0) where it compares both date and seconds, but i want only date part.
I have a date textbox. It has three validators on it. One is RequiredFieldValidator, second is CompareValidator and the third is RegularExpressionValidator.
CompareValidator checks for LessThanEqual for current date. For example if user enters date greater then todays' then it should display error message. It does that.
Problems is if user enters invalidate e.g., 2009/05/0d then I see two error messages. One for invalid date and one for compare. In this specfic case I want to see only one error that 'Date is invalid'. But some how I see two mesages.
iam having two text box for password and confirm password in usercontrol i want to validate these control using compare validator in mvc whether any difference is there between the ordinary .aspx and .ascx while using this compare validator.
I have a compare validator datatypecheck that was set up to check the date entered. I am now changing this to check to make sure that the date/time entered is valid. I changed the binding to be the date and time. I am not seeing anything that I need to change on the compare validator.
When I run the program and enter a date and time into the textbox, it is giving me the error that it is an invalid date. What am I missing?
I have a textbox control with a calendarExtender. I want to make the user select a date subsequent to Today. I have a public function, called display_error, written that displays some text in case of validation not successfull. So in this case, the validation of the date inserted by user would look like [Code]....
So, my textBox.text is a string, which I need to convert to Date to compare it to Today. Here's what I've written [Code]....
I've tried different methods, like Parse, but I keep getting the same error, String was not recognized as valid DateTime.
