View 2 RepliesHow can I disable the code behind validation when javascript validation is present? Then if there is no javascript enabled then the code behind validation will do its thing. What I notice is that it's reading the code behind valdiation not the javascript.

View 1 RepliesI am developing a website using asp.net and C#.I am using a RadioButtonList control. The code snippet for RadioButtonList is shown below
<asp:RadioButtonList ID="RLCompareParameter" runat="server"
RepeatDirection="Horizontal" meta:resourcekey="rsKey_RLCompareParameter"
AutoPostBack="True"[code]...
There is a button in the same page. While clicking on that button i want to display an alert message based on the selected radio list item using javascript. Some part of my javascript function is shown below
var RLCompareParameter = this.document.getElementById("<%= RLCompareParameter.ClientID %>");
if (RLCompareParameter.SelectedValue == "Forms") {
if (document.getElementById("<%= lbAvailableForms.ClientID %>").value == "") {[code]...
But the if(RLCompareParameter.SelectedValue == "some value") always false. i think there is no attribute like selected value for RadioButtonList control.
I am trying to validate that each radiobuttonlist has been selected. the radiobuttonlist is dynamically created from a sql database. The following line errors out "if (MyRadio[j].checked) {", the error is "checked' is null or not an object". The following is the code.
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder2" runat="Server">
<cc1:TabContainer ID="TabContainer1" runat="server" ActiveTabIndex="0" CssClass="ajax__myTab" Width="100%" ScrollBars="Horizontal">
<cc1:TabPanel ID="TabPanel1" runat="server" HeaderText="" Enabled="true">

I'm posting this here because my question isn't really about the javascript itself but about the workings of the RadioButtonList control. I have a webforms application where a several radiobuttonlist controls are rendered dynamically from server side code. I want to also render an undo button that will clear the associated radiobuttonlist. I can get it to work fine using an image button that does a postback. However, I'd like to do it without the postback, waiting until the entire form is filled out before posting back via a submit button. I've been able to get it to clear the radio buttons via javascript. However, when I click submit to post back to the server, the server thinks the radiobutton is still selected. Here's a condensed version of the code thatrenders the controls.
[Code]....
At run time, the radiobuttonlists and their associated undo buttons are rendered just fine. If the user selects an option from a radiobuttonlist and then decides they didn't want to answer that question, they can click the undo button and in the browser the correct radiobuttonlist is cleared. However, when they submit, it still saves whatever value they had clicked before to the database. It's as if there is something else on the page that is holding on to the selected value in the radiobuttonlist even after the javascript clears the control itself.
If we are using ASP.NET Radiobuttonlist in our page it becomes a little difficult to find the instance of it through Javascript because it is rendered in a different way in the browser ( the code is reproduced below )

I'm at my wit's end when it comes to this. JavaScript definitely isn't my strong suit and I've been trying to google for a solution. Here's the code I have:

What I want to do is whenever you click a radio button on the Group1Most RadionButtonList, it will disable the corresponding radio button on the Group1Least RadioButtonList. The problem is I can't figure out how to select an individual radio button within the RadioButtonList.
I have a scenario where a RadioButtonList needs to be in disabled mode by default and then on some event on client side, say, when a checkbox is checked, it needs to be enabled.
But once I disable it from code-behind, the javascript part of enabling it doesn't work.
When to go for custom validation control and when to do validation in javascript? What are pros and cons of each of them?
View 3 RepliesI have used a radiobuttonlist to enable/disable the textbox in Grid View. I did this using javascript onclick event.

It is working fine when the page get refreshed too.

Then in a scenario, I have removed the radliobuttonlist items (items 2 and 3) dynamically. For the first time when its loaded its working without flaws. After a page is refreshing due to any serverside events, the javascript to enable/disable textbox is not working.

I have verified the HTML file, the radiobuttonlist is loaded without the onclick event.
I was wondering, is there a way to set selecteditem in RadioButtonList using javascript (Client-Side) ? Is there an easy way to do that ?

I have custom control with ASP.Net validators.
writer.AddAttribute(HtmlTextWriterAttribute.Onclick, "javascript:return DoSmth();");
function DoSmth() {
var cBox = confirm("Are you sure?");
if (!cBox) {
return false;
}
else {
//Invoke validation
}
When I push button submit, I call confirm box. If I press cancel - all right. But if I press ok, I need to do validation. How can I stop postback and do valiadation?
I am currently looking a valiadation controls in javascript and ASP.NET and have come across the new MVC "jquery.validate.unobtrusive.js" which appears to use the data tags in the HTML to do the validation, is it possible to use these in standard ASP.NET (none MVC) as my logic seems to indication you can (by adding the appropriate data tags) but I can't find any referrance to using the library outside MVC

I'm using some of the typical ASP.NET's Validation Controls in my website. Now I'm trying to disable the JavaScript in my browser to test my application and of course the Validation Controls no longer works. I think it's best to try to make them work using one of the solutions down here instead of reinvesting the wheel and build a validation layer for the page or my objects -Am I thinking right?-
What do you think of these options and why:
Include in clicked button's event a code to check if the page is valid and if not explicitly call the Page.Validate(); method Check if whether the JavaScript is enabled and if not I should call Page.Validate();
I'm using asp.net validation controls which work fine. I've since introduced an HTML checkbox which should be ticked before the form can be submitted. My function for this reads as follows:
function terms(form) {
var terms = document.getElementById("chkTerms").checked;
var errorsArray = new Array();
if (terms == false) {
//alert("Terms not checked (works)");
errorsArray.push("You must agree to the terms and conditions.");
if (errorsArray.length) {
document.getElementById("termsOutput").innerHTML = errorsArray.join("
") + "<br />";
return false;
}
}
else {
document.getElementById("termsOutput").innerHTML = "";
}}
It is called as follows:
<asp:Button ID="btnSubmit" runat="server" Text="Submit" OnClientClick="return terms(form)" />
The problem I have is seems I can either use the asp.net validation OR the custom checkbox validation I wrote. After the form posts however, the asp.net validation fires!
I have one textbox and two checkboxes with a submit button. I want to put a customvalidator which shall call a javascript for the following condition -
If textbox.value > 0 then checkbox1 = checked or checkbox2 = checked. If neither checkboxes checked when textbox.value > 0 then raise error.
