difference between using asp.net validator controls vs JQuery for front end validation? What happens if the user turns off javascript on their browser?
View 3 RepliesI have a good number of regular expressions used for validation. Instead of manually typing in many addMethods for each regex, I tried using a loop. I have the below simulated struct to hold the regex name, RegExp object and validation message.
function RegExs(exprName, expr, exprVM) {
this.exprName = exprName;
this.expr = expr;
this.exprVM = exprVM;
}.......

I'm trying to use a field validator to make sure one of my list boxes has a selection before the user is able to proceed to the next page. i'm having is that if the validation message is triggered, all of the buttons on my page loose functionality.Meaning, if I purposely trigger the validation control, I can't get rid of the error message and none of my buttons do anything when clicke after this.
The majority of the HTML:

View 2 RepliesIs there a method in jQuery that I can customize an invalid validation myself instead of using jQuery plug-in validation?
For example, if the form is valid do this below.
$('form').validate();
if ($('form').valid()) {
//do something
};
But if I wanted to have a cutomize invalid method I could do this below.
$('form').validate();
if (!x == y) {
$('form').valid() = False; //[:(]
alert('Form is not valid.');
};
I have Doubt in Ajax Control Kit.
In asp.net ajax we have controls Like,Tabcontainer,TextBox Watermark,Toggle Button,Password Strength etc..., and same Functionality/Controls also there in Jquery.. and Jquery does this in client side itself and what's the use of having the control in Ajax Control ToolKit(Server Control).. and what is main Difference?I think Jquery more efffective than Ajax Control
I was referring muddasar's one of the article for the validation. Below is my code and i am trying to validate the file upload selected file format on the submit button. I have 4 upload control and fu1 is mandatory field and others are not mandatory fields. Though i need to validate all the four uploads if the files have been selected. My full sample code is below for easy testing,
<asp:FileUpload runat="server" ID="fu1" />
<asp:Label ID="lblMessage1" runat="server"></asp:Label>
<asp:FileUpload runat="server" ID="fu2" />
<asp:Label ID="lblMessage2" runat="server"></asp:Label>

I am doing slight mistake on the return to the main function. if i test indvidual function it works fine. whereas if i include the 4 functions in one function with the return statement, it's not validating. goes to to the server.
I've been trying to get a custom validator component working that ensures at least one checkbox from a checkboxlist has been checked. I've been used some code I found on dotnetjunkies.com but the client-side validation didn't work. I've been attempting to modify it to get the client-side javascript validation to work with no luck. Basically, I compile the below code into a DLL and add it to my bin folder.

I have Dropdownlist whose value field and text field are bind at runtime. it has --select-- as first item with a value of '0' and the rest of the values are bind at runtime.
I have given validaton group for both the control and the validator as "g1" and Intialvalue=0
But still the page is posting back even if I select '--select--' option.

I have inserted a login page using createuserwizard. but RequiredFieldValidator and CompareValidator does not perform at all and even all textboxes are blank, page is submitted and a record created in database
View 3 Replies I have a user control with a label and a field. I add the user control dynamically to a page at run time. There could be many user controls which are built dynamically from data I get from the data base. The data describes the label name and if the text box should be completed.. ie is it required. I have a submit on the main page which has a validation group.All the validators on the user controls have the same validation group. So far so good I hope.
The user control has a RequiredFieldValidator for the text box and looks all like this. The validator is enabled by default.
<asp:TextBox ID="dfControl" runat="server" Text="" ToolTip="ucsAlphanumericEntryDC" Width="95%" CausesValidation="true"/>
<asp:RequiredFieldValidator ID="rfvContol" runat="server" ErrorMessage="Value is required" EnableClientScript="true"
ValidationGroup="ValidateContols" ControlToValidate="dfControl" Display="Dynamic" Enabled="true"></asp:RequiredFieldValidator>
When I dynamically load the control I check a parameter to tell me if the field is required or not. The paramater is from the database which represents the control that I am about to draw. If the Field NOT a required field I disable the validation in the page_preRender.. also tried it in load.
if (!DisplayRequired)
{
rfvContol.EnableClientScript = false;
rfvContol.Enabled = false;
dfControl.CausesValidation = false;
}
So far so good. This all works on the client side validation for only the user controls with the Display Required set to true, leaving the Validator enabled.however on posting page from a submit button which I have wired to the same validation group as the user controls, I check the IsValid on the submit and if its false I dont save anything. But when the page re-renders on the client.. I have error messages on all the user controls, saying that they are required... even though I disabled some of them that where not required. the View state is default on the control which I assume to be on.
I also tried not redrawing the controls with the validators, by enclosing the code in a if(!IsPostBack)
why the validators fire when they are disabled on the first page load but dont get disabled on the postback.

View 1 RepliesI've got a free text form for people to submit feedback/support requests. ccasionally people will past in a support ticket or error log that contains something that triggers the .NET page validator as an XSS attempt. This takes the user to the error page as if the site choked on their input.Preferably, I'd rather have the page do some client-side validation when they press the save button before it's actually submitted.Is there a regex or some method I can hook into that would do the same basic check on the client side, or will I just have to write a regex that disallows certain characters all together like < and >?
View 1 RepliesI have come unstuck with a simple compare validation.
I have the following code
<asp:TextBox ID="tbxHowMany" runat="server"
style="z-index: 1; left: 310px; top: 385px; position: absolute; text-align: center;"
Width="75px"></asp:TextBox>[code]....
So when a user enters a figure higher than 200, the validation appears.However, when I change this figure to say, 30, the validation remains. I must be doing something really stupid, I just don't know what!
UPDATE: I have also just noticed that this validation occurs when a number greater than '20' is entered into the checkbox. I'm not very confused. I am assuming this is a type issue?
I have a custom validator:
<asp:CustomValidator ID="QuestionValidator" runat="server" ErrorMessage="Please select an option" ClientValidationFunction="QuestionValidator_ServerValidate" OnServerValidate="QuestionValidator_ServerValidate" ValidateEmptyText="true"></asp:CustomValidator>
[code]...
When I run the page, there is no validation and no error message. Please can you point out where I am going wrong, I'm suspicious it is at Page.Master.FindControl("form1").Controls.I have previously done such validation by looping through controls via form1.controls but this is unavailable as the page uses a form passed down via the master page.
Here is a code for my web form control
<asp:TextBox runat="server" ID="txtUsername"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" ControlToValidate="txtUsername" runat="server" ErrorMessage="RequiredFieldValidator"></asp:RequiredFieldValidator>
<asp:CustomValidator OnServerValidate="checkUsername" ID="CustomValidator1" runat="server" ControlToValidate="txtUsername" EnableClientScript="true" ClientValidationFunction="checkUsername" ErrorMessage="CustomValidator"></asp:CustomValidator>
Client side validation
<script type="text/javascript">
function checkUsername(source,args){
alert("test");
/* alert(args.Value);

View 1 RepliesjQuery validation is working fine on my machine, when i pushed it to test server it won't it's throwing some errors which is kind of surprising.These are the errors I am getting: $.validator is null or not an object...I've never gotten this error before and it throwing an error when I declared a variable like var isValid.I don't know what to do. I am doing the custom validation methods not in the document.ready(). Does this cause this error? I wonder because all jquery validations are passing and hitting the server side validations.
