How To Get Same Validators Control To Both Client Side And Server Side
May 20, 2010For the ASP.NET validator controls, I want to use both client-side validation for the user experience and server-side validation to guard against hackers. ASP.NET documentation leads me to believe that if EnableClientScript="True" then there will be no server-side validation if client-side validation is possible for the user agent. To get server-side validation, the documentation says use EnableClientScript="False", which bypasses client-side validation altogether.
Am I misunderstanding how the validator controls work? I ask because it seems obvious that many developers would want both client and server side validation together, and I find it hard to believe both together is not possible with one of the standard validation controls.
If I am understanding the ASP.NET documentation correctly, then I can find only two options:
Use two validator controls exactly the same except for their ID and EnableClientScript properties. Obviously ugly for maintaining two controls almost the same.Write some code behind to check if postback then invoke the Validate method on the validator group. Why write code behind if there a way to be automatic from the control?
Is there a way to do so using a single validator control with no code behind?

MVC :: 3 Remote Validators Client Vs. Server Side?
Nov 12, 2010First of all, awesome job in the MVC 3 RC. The Razor view Intellisense, validation improvements, and many other things are most excellent.A question to those who have struggled with complex validations like me (it led me to pursuing Ajax-based validation using a 'roundtrip validation' concept...http://mvcajaxvalidation.codeplex.com/)... I couldn't wait to have a pure client-side jQuery method that was well integrated with data annotations so I could drop the work-around attempts.So, I was excited to see how easily and well Remote Validation works. In fact, the way I could pass other fields along with my validation request was unexpectedly awesome. However, I was very surprised when I turned off JS and noticed that the data annotations which allow the Remote Validation check do not work server-side like all other data annotations that I've tried. Are there any plans to include this? I don't mind doing a custom validator just for the server-side, however, it will be a somewhat redundant annotation unless I'm missing something?
View 3 RepliesUsing Server Side Validators With Modal Dialog (jquery)?
Dec 2, 2010Is there a straightforward way to use server-side validation with ASP.NET's validation controls in a form that's displayed in a modal dialog? I am using jQuery and SimpleModal (in C#, VS2010, .NET 4.0)I've got a modal form which works fine. I need to use a server-side validation because the logic depends on data specific to the record being accessedMy solution for the project I'm working on now is to use a jQuery ajax call to pass all the form data to the server and get back the validation results before allowing the post to proceed. But this is relatively time consuming to implement, and in some situations I'm dealing with now all the validation code exists already.
The first challenge is that of course the modal dialog will close on a full postback. So you could put an UpdatePanel inside the dialog... without even thinking about this too much, though, I assumed that it wouldn't work out that well. It doesn't. And the form which opens the modal dialog to begin with is already in an UpdatePanel, which further confuses matters.Anyway, I tried putting the contents of the modal form in an UpdatePanel for the heck of it. It does actually do a partial postback, the dialog remains open, but the contents of the dialog do not get updated with anything I change server side. If I close and re-open the dialog on the same page after testing the validation code, though, its contents are in fact updated to reflect these changes. Obviously the way the dialog is rendered is confusing ASP.NET. Or vice-versa. But this just seems sketchy from the get-go.
Rather than trying to hack my way through this problem I was hoping that others had some suggestions about a better way to approach this. Or just tell me I'm trying to hard too mix apples and oranges and I should keep it all client side (or client side + jQuery ajax) if that is the only sensible thing to do.
Disable A Checkbox In Javascript And Recognize It As Checked On The Server Side?
Mar 17, 2010I have a checkbox which in some cases may be disabled and checked using javascript, i.e:
var cbTest = document.getElementById("CheckBoxTest");
cbTest.disabled = true;
cbTest.checked = true;
However, when sending a postback, CheckBoxTest.Checked is false on the server side.
Is it possible to disable the checkbox and still have the server side recognize it as checked?
C# - Show Only Client-side Validation With Client And Server Validators?
Dec 12, 2010If I have something like the following:
<asp:TextBox id="test" runat="sever"></asp:TextBox>
<asp:RequiredFieldValidator runat="server" ControlToValidate="test"
ErrorMessage="Required"></asp:RequiredFieldValidator>
<asp:Label runat="server" id="lblStatus"></asp:Label>
if in the code behind, I set the label to "You must enter a value if the textbox is empty" to validate it on the server side and this is fine, but if javascript is enabled, I don't want to show the client side validation and the server side label together. Is this something where I would just have to disable the client-side validators if javascript was enabled?
VS 2010 Client Side Validators?
Nov 18, 2010Given an ASPX page with a textbox, a requiredfieldvalidator, and 2 buttons.If I want to only have the requiredfieldvalidator validate that data is in the textbox if button1 is clicked but not button2, is my only option to set EnableClientScript to false and do validation on the postback?Or have they implemented a way where you can still do the client side validation, but specify for it to only occur if button1 is clicked and not button2?

View 3 RepliesHow To Ensure Validators Fire Before Call Client Side Javascript
Feb 4, 2011I have an asp.net application with basic CRUD functionality. On a page where i am capturing customer details i have several asp.net validators to required fields. I have attached a JS confirm box on the asp.net save button for the form. The trouble is that when the user leaves required fields unfilled and clicks the save button, the JS confirm box comes up, when the ok button is clicked, the save method is called successfully and only after this happened do the asp.net validators fire and display that required information has been left out.

Nov 5, 2010my problem is that i have a dynamic controls(text boxes) that are generated depending on a dropdownlist
and upon generating the textboxes i have created a required field validator and associated it to the text box that is being generated,
when javascript is enabled in my browser, the client side validation works fine, but when i disable the javascript.. no server side validation occurs and the Page.IsValid gives true when the method Page.validate() is fired
i tried a new simple page with dynamic controls and seems to work fine, but i could not figure out whats wrong with this page.
private void generateFarmForm()
{
int numberOfFields = 9;
Label[] labels = new Label[numberOfFields];
TextBox[] farmt = new TextBox[numberOfFields];
[Code]....
also the button that submits the form back has the same validation group,,, yet no luck with this... the page is in a content tag of a master page if this has any relation to the problem

View 4 RepliesWeb Forms :: Server-side IFrame Not Truly Server-side?
Mar 4, 2010I was reading about the fact that you can turn an IFrame control into a server object if you give it the runat="server" attribute. So I did that, for the purpose of running a website WITHIN our network. What I mean is that I want the site that loads INSIDE the frame to be loaded from WITHIN our network's IP address, and not the remote location's (browser's) IP address.Does this not work this way or am I barking up the wrong tree with IFrames?
I have a situation with dozens of remote locations, many of which I cannot easily get static IPs for, using a web based service that has IP restrictions in their hosting environment. I am essentially trying to, via our web server, FUNNEL all the users in the field through our network via an IFrames webpage, so that they can access this service which requires static IPs. They are okay with this, at the service we are using, if I can get this idea working.
VPN is not an option. These users are ehhhhh... no comment. For that matter, I don't feel comfortable with these remote users being on my network as anything but a port 80 web user, because of the potential for viruses.
