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...Server Side Validation vs Client Side Validation
If your page is using client side validation for required fields, expressions, etc. What are the benefits or disadvantages of using 'extra' server side validation for max lengths, parsing, etc?
Both have their Advantages and Disadvantages... so give this a read http://www.dotnetexpertsforum.com/viewtopic.php?t=172 Regards,Vinz"Code, Beer and Music" that's my way of being a programmer!How to get your Forum Question Answered | Blog | CodeASP.NET
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...Using Validation COntrols, client-side validation ignored
I have a simple ASP.NET 1.1 app with some text boxes. I have used RequiredFieldValidator controls and they work fine on localhost. That is, there is no posting to the server if a field is empty. However, if I upload the app to my hosting service (WebHost4Life), the client-side behavior does not take place and the page is posted to the web server (were the expected server-side validation takes place). Any idea why this might be happening (the hosting service does have the appropriate js that should be being used client-side for the validation.)

I have a form which comprises of several form inputs, which are being validated using standard requiredfield & regular expression validators. A summary control is placed to display all server side error messages and is also set to showMessage = true for client side prompting.
Now I get to the tricky bit, I include a custom validatio...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...Validations client side or server side ???
Where should the validations (Required field, range, etc.) be done in an web page client side or server side?

Hi all,I have a web form with a few controls and reqdfield, compare & regex validation controls. On all validation controls i have enabled the client script property. Yet when I submit the form it does a postback to do the validation. Any ideas? I am running vs2005 beta 2.TIA!
Hello.how do these validators perform the validation of the other controlos? whar browser are you using?-- Regards,Luis Abreuemail: labreu_at_gmail.comEN blog:http://msmvps.com/blogs/luisabreu
Well they are regular requiredfield, regex & compare validators. Browser is latest version of Firefox. I had to use...Validation control not doing server side validation?
I think the subject covers what I'm asking. I want to run some checks on the data that was entered after the page was submitted, but I don't know how to handle it if there's a problem the user has to go back and fix. So I thought I'd try to work around the validation control to see how .NET handles it. I have a text field that is required. When the submit button is clicked, I assume some client side validation is run. I get the validation message I want and the form won't submit. But then I made a change in the on click event of the submit butto...Client Side validation of Calendar control prior to server side selectionchanged event code
Any thoughts or suggestions regarding this will be greatly appreciated.
I have a Calendar control with the validation constraint(can't enter appointments on Holidays or on Thursdays). To create a smoother experience, I'd like for this to be done client side.
I have multiple usercontrols each displayed by pressing a button and then change the apperance to a new user control and so on. I have to check that almost every field in this user controls have a value entered, and then indicate (e.g. with a red star) those textboxes that does'nt have a value entered. How should I do this in the best way, client side or server side with some validator? I have in mind that when using a server side validator, it may dissapear when making a postback. But I'm not sure, and I assume there is a way to come around this problem?What do you all say? Client side or s...client side and server side validation
