A Foolproof Method to Dynamically Toggle HTML Checkbox in ASP.NET Using JavaScript

Although there have been numerous inquiries related to this subject, I haven't been able to find a solution specific to my situation.

I currently have a gridview that contains checkboxes. What I'm trying to achieve is that when I select the checkbox for exp_id 1515001101, all other checkboxes for that same exp_id should automatically be selected as well.

     function checkUncheckHeaderCheckBoxforSubmit(obj) {
 var checkboxCell;
 var expidCell;

 var grid = document.getElementById("<%=grdViewLocalConvence.ClientID %>"); 
 for (i = 1; i < grid.rows.length - 2; i++) {

    for (i = 1; i < grid.rows.length - 2; i++) { 
     checkboxCell = grid.rows[i].cells[8];
     expidCell = grid.rows[i].cells[0];

     var exp_id = expidCell.innerText;

     for (j = 0; j < checkboxCell.childNodes.length; j++) { 
        if (checkboxCell.childNodes[j].type == "checkbox") {  
             if (checkboxCell.childNodes[j].checked == true) {
                var exp_id = expidCell.innerText;  
                 GridVwHeaderChckbox.rows[i].cells[8].getElementsByTagName("INPUT")[0].checked = 
                   exp_id.checked;
         }
       }
      }
    }
 }

I would greatly appreciate any assistance. Thank you.

Answer №1

Here's a suggestion for you:

 $(".checkboxid").change(function() {// This is the code that checks the first checkbox
        if(this.checked) {
            $('.checkboxid').attr('checked', true);// Automatically checking other checkboxes with relevant details should go here
        }
    });

If you want to ensure that the state of these checkboxes remains the same, it would be best to save the data to a database and retrieve it every time the page loads.
