Validating calendar dates in textbox asp

NET AJAX control that is associated with a Text Box control.

In the above code u r giving the Calendar Extender property On Client Date Selection Changed for date validation. Add(“onkeypress”, “return numerals Only(event)”); txt Created Date. I can set Range validator since my from or To date changes dynamically. I achieved this through Text Change i want to know how to disable the dates which is populated in Ajax Calendar based on my from and To date at run time on script,since we can write script in Ajax Calendar Extenders On Client Showing Event… It is getting error for using validator The value ’23/6/2011′ of the Maximum Value property of ‘validdateofbirth’ cannot be converted to type ‘Date’. my question is how to get the number of days in another textbox.

When setting options via HTML attributes, remember to enable the validator by setting data-fv-date="true".

You don't need to do that when using HTML 5 type="date" attribute (the format then will be forced to be YYYY-MM-DD).

This tip was shared by one of the Microsoft® support person at the forums.

There could be instances where you do not want the user to select a day earlier than the current date.

There are two ways to do it : 1) Using Javascript (with our Calendar Extender) 2) Using Range Validators for our textbox Using Javascript: The Calendar Extender has a property called Using Range Validator: Since we use a Text Box control to display our date once we choose from the calendar or to manually input the date, Range Validators can be used to check whether the date is within a given range (minimum & maximum). Does anyone here know a javascript/jscript magic to collapse?

Below is the code for Range Validator : With these two methods you can easily validate the date. Hi, Ajax Calendar control is Excellent when you use it with a single textbox.

The user can then set a date by clicking on a day, navigate months by clicking on the left and right arrow and perform other such actions without a postback.
