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.
I found this article [URL] on how to create a customvalidator for the checkboxlist. Followed all the way thru, but when i load my page i get the following error, how can it exist in 2 places? How can i resolve this to use the validation on the page?
Compiler Error Message: CS0433: The type 'CustomValidators.RequiredFieldValidatorForCheckBoxLists' exists in both 'c:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files

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 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?
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.

for the radiobuttonlist control, when I try to style individual buttons with 'span'I get a error, is there some way to style each button?

error is:

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:

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'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) {

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?

View 1 RepliesI'm working on the admin tool and am using DetailsView to edit the records (.net 2.0). In the screenshot below, the left is the GridView, and the right is the DetailsView. When a user clicks "Select" in the GridView, I am trying to display the assigned Sectors stored in the database via a checkboxlist (activities can have multiple sectors). This way, the Admin user could just uncheck/check what sectors they want to change. Unfortunately, I can only get the first sector that's stored database to show up.
Is it possible for the Checkboxlist control to allow for more than one box to be checked at the same time? If so, do I need to create a custom funcion (via looping) in order to populate the checkboxlist accordingly? I've ran into 3 articles so far that imply that, but can't get the For Each to work for my situation:

<div> element with fixed width contains CheckboxList control. Since ListItems can be added by users to this control, there's a possibility that particular ListItem could overflow parent <div> due to having too large text. I've tried preventing this by setting overflow property:
<asp:CheckBoxList ID="chkAllRoles" style="overflow:hidden;" ... />
but to no effect. Is there some other way to prevent ListItem from overflowing?
