Check & Uncheck chkboxes in nested repeaters using Jquery
Sep 2 2013 8:09 AM
Hi,
In our Appln we have two nested repeater controls.the parent control had parent chkboxes.and the child repeater had child subcategory check boxes.we need select and deselect all child chk boxes when a parent chkbox is selected and vice-versa..and even if a single child chkbox is selected we need check the parent checkbox......Using Jquery/JavaScript..
the following jquery i used but its not working ..all the child checkboxes of all categories are getting selected or deselected when any single parent category chkbox is checked.
$(document).ready(function () {
//This will add one function to be called on every request of the update panel
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
//initiateCheckAllBinding();
});
function EndRequestHandler() {
var allCheckbox = $("#allCheckbox input[id*='chkSelectAll']");
var checkboxes = $("#Subcategory input[id*='chkChild']");
alert(allCheckbox);
allCheckbox.click(function (e) {
alert("123");
checkboxes.attr('checked', allCheckbox.is(':checked'));
});
checkboxes.click(function (e) {
alert("321");
var rowCheckBoxSelected = $("#RepeaterTable input[id*='chkChild']:checked");
if (rowCheckBoxSelected) {
allCheckbox.attr("checked", false);
}
else {
allCheckbox.attr("checked", true);
}
});
