My web page uses a number of custom validation controls to check that values have been selected in DropDownList controls. I have written simple Client side scripts and also server side, but the validation control never gets fired. I am performing validation using a button-click that has CausesValidation set to true.

have a CustomValidator that I am trying to use. I have a couple Validation groups so I set those 2 different groups up in my case. The CutomValidator is validating the field when I click the button and it puts out the error message however its letting the button event insert the data.

I've set up a CustomValidator with a ClientValidationFunction as:
<asp:CustomValidator ID="CustomValidator1" runat="server" Display="Dynamic" EnableClientScript="true" ClientValidationFunction="checkClients" ErrorMessage="You must select at least one client or staff" SetFocusOnError="true"></asp:CustomValidator>
<script type="text/javascript">
function checkClients(sender, args) {

Sample code below. Either I am doing something wrong or missing something in 4.0.
1: The function CheckText fires upon button click in IE but not in FF.
2: The function CheckText fires upon button click in IE /FF when the site runs under 2.0 or 3.5.

I have a Gridview with a number of Template fields, where the values are all binded to a DB.
I can handle the validation in the codebehind (C#) fine, as far as that singe control.
BUT
I want the validation to be dependent on one of the controls in a Different TemplateField
ie.
Template A
Template B
Template c
Template B & C dependent on Template A
How do get the value in the JavaScript function identified in ClientValidationFunction property that was entered in the control that was identified in the ControlToValidate property of a asp:CustomValidator control?
function MyValidateFunction(sender, args) {
//want to get value of MyControl
}
<asp:CustomValidator
ID="cvAlarmedLocationAddress"
runat="server"
ControlToValidate="MyControl"
ClientValidationFunction="MyValidateFunction"
Text=""

I have placed a customvalidator in my listview control in the InsertItemTemplate. I want to make a check before the insert is done and set the validator to false if the test fails. I placed the code to check this in a click event routine that fires when the "Insert" button is clicked. When the code tries do a FindControl for any controls in the ListView, I get an error saying, "Object reference not set to an instance of an object."
Here is the code:

I want to use CustomValidator for CheckBoxList web control. I tried the code found on:[URL]
But it is not working for me. Nothing happens. No error.
My code (based on the provided link) is as follows:
[Code]....
But it doesn't execute client side CheckItem2 method.
VWD 2008 Express. Visual Basic.I have a customvalidator on my page and a corresponding OnServerValidate routine tied to this control in my VB code behind. I also have a "Save" button that is defined as "CausesValidation=True." I placed a breakpoint in my OnServerValidate code for the customvalidator and a breakpoint in my OnClick routine for the Save button. What I expect to happen is that when the "Save" button is pressed, all the validation is checked before ever entering the OnClick code for the Save button. If any of the validators are false, then I expect that the Save button OnClick code will not run.

I have a simple form that uses jQuery validation to notify the user of input errors, etc. When I add an ASP.NET CustomValidator to the form, it causes the page to postback and skip the jQuery validation. I need the form to not be submitted to the server until the client-validation is correct. Has anyone seen this before?
This is my form:

I have a fairly complex master/content page that has several GridViews - each one in its own UpdatePanel. I also have four CustomValidators on the page, each one assigned to a different
ValidationGroup. Two of the CustomValidators are buried inside a HeaderTemplates of a GridView (inside a distinct UpdatePanel). In the EmptyDataTemplate, HeaderTemplate and FooterTemplate of each GridView I have ImageButtons that postback to the server to perform some operation. All the ImageButtons take this form:
[Code]....
When I click on the ImageButtons in one of my GridView's the ImageButtons cause the ServerValidate event of two CustomValidators to fire. The server-side OnClick event of the ImageButton never fires. I have verified that the ImageButton(s) have CausesValidation="False" - what could be causing the validators to fire?

I have a login control that is working beautifully on my localhost, but not working on the server. It validates my username & password - and gives me an error if I enter an invalid username/password. However, if I enter the correct username/password, the page refreshes, but does not redirect me to the "ReturnUrl" that I see in the URL. I've seen posts on this, but nothing that I tried worked. I've tried setting the 'MembershipProvider'attribute of the login control. I don't want to set the DestinationUrl...I want it to take what is in the ReturnUrl in the querystring. I don't think it's a web.config issue cuz it works on localhost??
View 3 Replieshow am I be able to display a text into a customvalidator control, say for example an asterisk symbol (*) for a new entry. If in case that, the inputted value is invalid then, I will place proper prompt text.
View 2 RepliesI have two CustomValidators, both of which function in the same way (call a query and check if a particular value is available in the DB), the only difference is the query itself.
Rather than writing the same function definition in the code-behind, I would like to find a way to execute a particular query depending on which CustomValidator called the function (I guess using the CustomValidator's ID) so if I have the follwing:

How can I create a CustomValidator on Client Side for validating my file path from FileUpload?
View 1 RepliesI am working with a page that has a series of checkboxes that at least one box must be checked.
The validator fires when I click the submit button and if no checkboxes are checked indicates the validation has failed. However If I check one of the checkboxes the validation message does not go away until I click the submit button again.
If I was using this on a control in which I had specified the ControlToValidate and I fixed the validation issue the error message goes away immediately.
However in this case I am not setting the ControlToValidate due to the neeed to validate serveral independent controls.
So my question is can I cause a re-validation of the custom validator? For instance I would like to add on each checkbox a onclick="revalidate()" that would then force the validation to happen again.
Here is some sample code that I wrote to demonstrate the scenario.
<script type="text/javascript">
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
