validation, is it better to have client side or use server side validator controls
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?
Hi!
If for server side controls you mean RequiredFieldValidator, CompareValidator, RegularExpressionValidator, etc.. i can tell you that they use client and server validation.
For instance if you use a RequiredFieldValidator, on the client will be a validation, but on the server this condition will be evaluated again. Probably one of the objetives of this is deal with client with javascript disabled.
Of course I ...
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...
Jscript, moving from client-side to server-side (.NET)
Hey all
I’m working translating a web-app written in client-side
Jscript to run on the server-side as JScript.NET. Without needing to get too
specific, I am using Jscript because the original page aggregated raw data to
produce statistical results (this was done dynamically based on user 'sort-by'
options). The final output is an html report that can be emailed.
Because this is currently being done on the client side, as
the raw data grows the load-time grows as well (to the point that has almost
become unusable). I’m posting here to see if anyone has any experi...
When to use client side varidation and server side varidation in .net?
In .net or classic web application we can varidate user data either on client isde or server side. How to select which side varidate to be used? Thanks!
Generally, I use both client and server validation. I make sure the input is in the correct format and reasonably valid on the client, then I verify the data on the server. The extent of validation also depends on the type of data that I need to validate.Here are a few references:Validating ASP.NET Server ControlsIntroduction to Validating User Input in Web FormsClient-Side Validation for ASP.NET Server ControlsSecurity Checklist...
web forms with client and server side controls??
Hi,
I have a form that has client and server side controls. I have a problem in that
any client controls (textbox) within the form runat="server" can not be accessed
with client side code.
Anyone got any ideas why and what work arounds are possible.
Regards,
Graham.
once a form element is inside a <FORM> tag, you can no longer refer to it by its ID alone.
you have to refer to it by formname.elementid or document.all.elementid.
use document.getElementById(yourtextboxid) to get a ref to the element in the form. using this allows u to bypass the formn...
communication between client side(java script) and server side in .net project
I have a question which is, when building a .net project, we are able to use server side code and client side code(java script). How do they communicate? Thanks
Client Side coding works with the WebBrowser. So when ever you write client side code you have to keep browser compatability in your mind and you have to code.
Server Side code works with Web Server (IIS) and it's ASPNET ISAPI's.
The won't directly communicate with each other. But using AJAX you can all server side code from Client Side!

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...

and diff server -side coding and client -side coding ?
please help
I have answered the first part of your question in your previous posting.
Server-side coding languages are ASP, ASP.NET, PHP, CGI (Perl) and many, many more. They are used to create dynamic web content (based on additional information that is attached to the request) and are often used to extract information from databases.
Client-side coding languages are JavaScript, VBScript, EMACScript and are used to create dynamic content that responds to the u...

server side controls in a non-server side form
I want to use server side controls in a non-server side form.I use server side controls (like dropdownlists) so I can fill them with the right options from the database.My question is, what is the best way to approach this?CAN I use server-side controls in a client side form? If so, how can I get the values contained in the controls when I do a post? (not in a querystring).Here's a sample of my code:
<form id="frmAdvancedSearch" method="post" action="advancedSearch.aspx">

Client Side validation of Calendar control prior to server side selectionchanged event code
Hello,
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.
The dillema is how can I intercept or precede the <asp:calendar> controls selectionchanged event from firing and run my client javascript; passing it to the server if validation succeeds for more intensive processing and database activity.
The clientside javascript will need the selected date to deter...
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...
