Hello, hope someone can  help me find a decent soultion to my problem. I have a form with 4 different radDateTimePicker, they are used to create an event. For each entry I have to compare the Date and time of the previous entry. Because of the control format Compare Validator doesn't work.

I'm using radCalendar 2.2.5

Description of the 4 Date Time Pickers

1) Date that the Event will be published (today and future date)
2) Date the Event Start (GreaterThenEqual then #1 Date time Picker)
3) Date the Event End (GreatherThen then #2 Date Time Picker)
4) Date the Event is Archived (GreatherThen #3 Date Time Picker)

I've thought of using two different controls radDatePicker and radTimePicker, but I will have to add too much client side to the form. My form already have over 60 controls.

Any help suggestion is welcome.

Thanks, Mario

Hello Mario,

You can use a CompareValidator to ensure that the second date is greater than the first one. This online example shows how to use CompareValidator with RadDatePicker/RadDateTimePicker control

I'm using telerik:RadDateTimePicker and the CompareValidator doesn't work with this control.

I copy the validator code from example and it doesn't work.

How can I compare two RadDateTimePicker fields ?

Hello Marino,

Can you please share your markup? We will review it and get back with our findings.

Thank you for reply.

I make some tests and detect that CompareValidator doesn't work with date and time. It only works with date.

To compare dateTime I need to use the CustomValidator and write a javascript function to validate the fields.

@Plamen, thans for your reply, however the link you direct me on is using Date Picker only, which has never been an issue for me.

I work with the Telerik objects since two years now, and I found that sometimes objects didn't react as expected. Most of the time I had to start to play with the object on a blank page and voila! it works on my original page. It has to do with versionning I guess, since I work in an environment where two to 5 developpers are working on the same project and someone update an object. We are using Source Safe for the past 12 years and honestly I start to dislike it. Anyhow here is the code I finally came with, pretty straight forward.

Each Date/Time entry is required and the following Date/Time is compare to the previous Date/Time. It works like a charm now :) This is with Version 2.2.5.
