View 6 RepliesWeb Forms :: Control Checkbox Selection From CheckBoxList Using Javascript?
Apr 19, 2010I am binding a checkboxlist with a dataset (with these columns :
id,empname,resourceId,balanceId as columns) with datavaluefield as id and datatextfield as empname;

2. And in total he should select only 20 items (max 5 items for same resource id and max 15 items for the remaining)

Web Forms :: Checkbox Is Checked Even After Unchecking; Javascript + Repeater
Apr 14, 2010I am using Repeater and i have checkbox in every row. I have to post all the rows to a DB Table.
The problem is:When i uncheck a row and then press the save button , all the rows are getting saved.
I checked with debugger that actually i see the checkboxes unchecked , but the debugger shows them checked.
Checkboxes have JAvascript onclick events associated with them.
[Code]....
My javascript function updates the labels on the page.My getvalues from repeater code is as follows. i am checking all the rows whether checked or unchecked.
[Code]....
why checkboxes are showing always true whereas they should have been false (as they are unchecked).
Web Forms :: Checking All Checkboxes On The Page Using 1 Checkbox With Or Without Javascript
Nov 1, 2010I have found plenty of examples where the checkboxes to be checked are within a datalist, gridview or other datacontrol like that.. but i dont have that setup..
I have individual checkboxes within my page and need to provide a way to check or uncheck them all..
I cant use a checkboxlist because of the layout of the page.. so not sure if it would be easiest with javascript or do it with the checked event for the single check box that will be used..
I know that may not be the best or cleanest way, but is there a better way?
Reason i cant use a checkboxlist for the larger set of checkboxes, is that a few of them will have additional fields that need to be completed if they chose certain checkboxes.. so i have those controls next to the checkbox that they belong with..

View 2 RepliesJavascript - Validating Against Checkbox And Validation
Jan 19, 2011I'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!

View 4 RepliesJavaScript - Check If A Checkbox Is Checked In A Group Of Checkboxes In Clientside?
Apr 3, 2011note that the scenario is ASP.NET Webforms + Master - Content page which mess up the ids.
I have, say, three checkboxes

CssClass="company"/>
<asp:CheckBox ID="chkConsultantEnvironment" runat="server"
CssClass="company"/>
<asp:CheckBox ID="chkConsultantSafety" runat="server"

I would like to make a div id="CompanyPanel" on click event of each checkbox according to the following condition
visible if any of the checkboxes are checked.
hidden if all of the checkboxes are unchecked.
I am planning to use jQuery since I am selecting by class name. I could do it with jQuery.each on the class='company' by checking each for a checked flag.
