Highlighting web form fields on validation error events (client-side)
Have anybody eventualy did that? This is a nice feature when the web form highlights it's input fields and/or lables for that fields if they are not validated (client-side). Unfortunatly, there is no such build-in functionality in ASP.NET 2.0 validation controls. But i'm quite sure that's it's possible to make on your own, what do you think?Perhaps an additional js script shoud be added on the buttom of the page which will redefine one or more functions of original js code.Any comments, thoughts, suggestions?My LinkedIn Profile - ASP.NET C# Ninja | My News Feeds

form double validation- server side and client side
Hi!
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...
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...
.net validators + client-side javascript validation, EnableEventValidation=false
Scenario:
1. I have a DropDownList, with 2 listitems in the .aspx. appenddatabound=true and it is tied to a datasource (via datasourceid), autopostback=false, onchange=checkIfAddNew(this) [this is the client side onchange event]The second option on this dropdown is "Add New", and the checkIfAddNew function pops up a new window and when it returns, it adds the newly created option to the dropdown. In order for this to happen without asp.net getting mad, EnableEventValidation has to be set to false in the Page directive. In addition to this dropdownlist, there is a RequiredFieldValidator...
Client Side Form Validation
What does everyone recommend for client-side form validation?
I really like the Validation Application Block in conjunction with the PropertyProxyValidator in Enterprise Library, but that requires an asynchronous postback.

What about the validator controls in Asp.net. You can also use them with AJAX (Validator callout)Vikram www.vikramlakhotia.comPlease mark the answer if it helped you

Server side validation affecting client side validation
Hi there
I have some client side validation that is working fine and enables/disables buttons based on user selections. This works great. However, when I perform server side validation using custom validators (like checking if the user has entered < HTML > tags or decimals in the integer boxes) and the server side validation returns isValid = false then all of the JavaScript validation that I've already done when the user clicked each control is lost. I don't understand why the enabled/disabled state of the control is not maintained. What is calling the JavaScr...

client side validation vs server side validation
hello
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")
else
response.redirect("Page is not valid")
end if
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...
Client Side Form validation
OK - I agree ASP.net validator controls are way kool. But I don't think they COMPLETELY replace the need for good old-fashioned hand-coded JavaScript client side form level validation. For example, say I have a form with 10 textboxes indicating possible percentage amounts for various elections in a 401K retirement account. The amounts need to add up to 100%, but only 1 box must be filled in, although all ten could be filled in. Thus we do not have a simple must enter scenario, and only with the click of the submit button can we validate that all the numbers do add up to 100%.
I see no...

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...
Showing and hiding Panels on the client side?
hello,
I have a couple of panels I am useing on a page to mimic a tab based navigation menu. I have been able to use linkbutton clicks to show and hide panels to simulate the tabs. Is it possible to do this on the client side rather than making trips back to the server? Is this similar to the UI validation controls that can validate input from either the client or server side, or would I have to write the script myself to accomplish this?
Thanks,
jigster...

Client-side validation through web service
Hi,I'm trying to write a form to create a new user. I have a couple ASP custom validators for the login name; one checks if the login name is valid (alphanumeric & correct length), and the other checks if the login name is in use. Both of these validators make calls to an AJAX web service. Script code follows: function isLoginNameInUse(sender, args) { var loginName = document.getElementById("loginName").value; Anything.Services.UserService.IsLoginNameInUse(loginName, onUseSuccess, onUseFailure); &n...
