Validating calendar dates in textbox asp

For example: when you are providing the user a form to book tickets, you would not like him to choose an earlier date.

To achieve this requirement, use the following javascript code. From the Extender Wizard, choose Validator Callout Extender.

Sometimes we need validation for date, that user can only put the date in textbox.

Here is a method through which user can only select the date from calendar extender.

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.

If you plan to do this programmatically, here’s some code for you.

Use the On Client Shown event and switch the mode using javascript.And yes, using both would sometimes lead you to race conditions where choosing a date from the calendar might be an invalid date and the Range Validators would immediately come to the focus. But how can we achieve needs like coparing the date from another texbox live Effectivefrom Date in one Text Box and Effective To Date in another Text Box whose values are driven from Ajax Calendar control dynamically. Http Exception: The value ’23/6/2011′ of the Maximum Value property of ‘validdateofbirth’ cannot be converted to type ‘Date’. I have two textboxes with Calendarextenders in each one, so when i choose a date from Calendarextnder1 it will show in the textbox1 and when i choose at Calendar2 it will show in textbox2 ..In the above code u r giving the Calendar Extender property On Client Date Selection Changed for date validation.

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. the first solution (Datepicker.aspx) doesn't work for multiple dates...I have seen instances where, when you use javascript to fill a textbox, the validators on the textbox do not fire (just on client side of course - you should always check on server-side as well).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?
