Validation Controls in .NET ( Client side or server side?)
i have a very basic question. We have all these validation controls in asp.net ( required field, range validator and others)..my question is the required field validator is a server side control. So does that mean that it does a post back?..is it client side or server side control
The only controls that post back are buttons and other inputs where you set AutoPostback="True", such as a dropdownlist or a textbox. Another way of posting back is using an UpdatePanel and placing a trigger in it for a specified control and/or event.
All controls are considered clien...form double validation- server side and client side
I would like to make a server side validation after calling a js function that makes the client-side validation.
I do not understand couple of things:
1. Do i need a server side button or a simple HTML submit button in order to call both of the tests?
2. How do i call a server side function which is written in csharp after i finish my JS validation (the submit button is calling the JS function for validation first.)- is it possible to call it directly from a js function?
3. I know that my toolbox on asp.net contains validation controls who probably are b...Server Side Validation vs Client Side Validation

i see a web form that consists of three controls :textbox,requiredfieldvalidator that weired to the textbox and a button
within the click event of the button there is the following:
if page.isvalid then
response.redirect("Page is valid")
response.redirect("Page is not valid")
according to my understandings:
when the user does not fill anything in the textbox and then clicks the button the the page will not be submitted (i.e no request to the page will be happened or no postback will be happened) then no server event will be happened so it is sure when the us...avoiding redundant server-side validation after client-side validation
I see an inaccurate validation behavior on my asp.net (2.0) form. The EnableClientScript property of my validation control is set to True by default, so it performs the validation on clientside. But as soon as this occurs, it also performs the server-side validation, so the page refreshes. When the validation error occurs on clientside, it should not do the validation on serverside (I'm not calling Page.Validate() or doing Page.IsValid). In my past experience, asp.net handled this automatically, but I guess it's not always the ca...client side and server side validation

Hi All. I want to do validation on text boxes etc. Is it better to do client side validation or just use the server side validation controls?
If for server side controls you mean RequiredFieldValidator, CompareValidator, RegularExpressionValidator, etc.. i can tell you that they use client and server validation.

I wonder if this is the right forum to post this question because it is an issue about both server and client side processing.
I am developing a web application (online store) which will run in a hosting company. Users accessing this app will be able to place orders with one limitation; the store has a schedule to accept orders. For example, it can be open from 8AM to 10PM and/or it can be closed on Mondays. I just can't validate time and/or day directly because time zone may lead to wrong results. So I thought about getting the schedule information, which is saved in my database, ...When do the validators kick in? Are they server side or client side?
Hello,I am confused. I was under the impression that asp.net validators work on the client side.But I was confused when I set the enabled property of validator to false and then the validator did not work. (RegularExpressionValidator1.Enabled = false;)But the other confusing thing to me is that if the validators work on the server side then when don't i see the page refresh like on other postback events? Kindly throw some light.Thanks!

Hey all,I have got this text box control on my webform, which has two validators.. 1. RegularExpressionValidator and 2. CustomValidator.Now, RegularExpressionValidator control works if I enable client-script. But somehow it does not work for server-side validation. Any idea why this is happening? This happens to another textbox control on other web form as well which has similar coding. So, to enable the validation at present I can only do client-side validation I guess. 1 <TD>
