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?
If for server side controls you mean RequiredFieldValidator, CompareValidator, RegularExpressionValidator, etc.. i can tell you that they use client and server validation.
Of course I ...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...Jscript, moving from client-side to server-side (.NET)
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??
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.
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!

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...Combining a server-side control with a client-side control!
I am trying to combine a server-side control with a client-side control.
I have created a listbox in both sides, the client-side control's code is:

The other one is the server-side control which has this code:

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.
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

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 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...
