I have GridView two column,  1 column is RadioButton and other is Checkbox,
I want based on RadioButton click in the same row checkbox should be checked or unchecked, in the following code if click radio button then all checkbox in the columns is checked.

<script type="text/javascript">


    function Check_Radio(rb) {
           var isChecked = rb.checked;
           var row = rb.parentNode.parentNode;
        if (isChecked) {
            row.style.backgroundColor = '#B6C4DE';
            row.style.color = 'black';
            
        }        
        
        var currentRdbID = rb.id;
        parent = document.getElementById("<%= GridView1.ClientID %>");
        var items = parent.getElementsByTagName('input');

        for (i = 0; i < items.length; i++) {
            if (items[i].id != currentRdbID && items[i].type == "radio") {
                if (items[i].checked) {
                    items[i].checked = false;
                    items[i].parentNode.parentNode.style.backgroundColor = 'white';
                    items[i].parentNode.parentNode.style.color = '#696969';

                }

            }

            if (items[i].id != currentRdbID && items[i].type == "checkbox") {

                items[i].checked = true;

            }                 
    }
    }  
</script>
How can be fix the problem..

Thanks

Hello Khalid,

The Check_Radio function iterates through all inputs and checks all checkboxes which have id different than the clicked radio button. If I understand correctly, you would like to check the checkobox only of the same row. Please correct me if I am wrong.

If that is the case, you could simply find the checkbox within the current row and set its checked property.

e.g.

      function Check_Radio(rb) {
        var isChecked = rb.checked;
        var row = rb.parentNode.parentNode;
        if (isChecked) {
          row.style.backgroundColor = '#B6C4DE';
          row.style.color = 'black';
        }

        $(row).find("[type='checkbox']").prop('checked', isChecked)

        var currentRdbID = rb.id;
        parent = document.getElementById("<%= GridView1.ClientID %>");
        var items = parent.getElementsByTagName('input');

        for (i = 0; i < items.length; i++) {
          if (items[i].id != currentRdbID && items[i].type == "radio") {
            if (items[i].checked) {
              items[i].checked = false;
              items[i].parentNode.parentNode.style.backgroundColor = 'white';
              items[i].parentNode.parentNode.style.color = '#696969';

            }

          }
        }
      }

Please try the above approach and let me know if it works for you.

I look forward to your reply.
