Hello, I have modified the code based on your requirement, please have a look. Important attribute is name="choose" which should be identical for all the radio button so it will only allow to choose one radio button at a time. div class = "col-sm-3" > input type = "radio" id = "LoginID" name = "choose" /> label for = "LoginID" class = "col-form-label" > LoginID label > div > div class = "col-sm-3" > input type = "radio" id = "SIS_ID" name = "choose" /> label for = "SIS_ID" class = "col-form-label" > SIS_ID label > div > div class = "col-sm-12" > input type = "text" multiple id = "eNtsaTextAreaDisc" /> div > button type = "button" class = "btn btn-secondary" data-dismiss = "modal" > Close button > button type = "button" class = "btn btn-primary" id = "btnNext" disabled > Next button > And Script (updated) "text/javascript" > $(document).ready( function () { // Fire when radio button clicked $( "#LoginID, #SIS_ID" ).bind( "change" , function () { checkdata(); }); // Fire when we enter anything in the textbox $( "#eNtsaTextAreaDisc" ).bind( "input" , function () { checkdata(); }); }); //here we check both radio button clicked and textbox filled with some information function checkdata() { if (($( "#LoginID" ).prop( "checked" ) || $( "#SIS_ID" ).prop( "checked" )) && $( "#eNtsaTextAreaDisc" ).val().length > 0) { $( "#btnNext" ).removeAttr( "disabled" ); } else { $( "#btnNext" ).attr( "disabled" , "disabled" ); } } Hope this will help!

HI, I have just re-write your code just to simplify. your HTML (with ids in controls) div class = "col-sm-3" > input type = "radio" id = "LoginID" /> label for = "LoginID" class = "col-form-label" > LoginID label > div > div class = "col-sm-3" > input type = "radio" id = "SIS_ID" /> label for = "SIS_ID" class = "col-form-label" > SIS_ID label > div > div class = "col-sm-12" > input type = "text" multiple id = "eNtsaTextAreaDisc" /> div > button type = "button" class = "btn btn-secondary" data-dismiss = "modal" > Close button > button type = "button" class = "btn btn-primary" id = "btnNext" disabled > Next button > jQuery Script "text/javascript" > $(document).ready( function () { // Fire when radio button clicked $( "#LoginID, #SIS_ID" ).bind( "change" , function () { checkdata(); }); // Fire when we enter anything in the textbox $( "#eNtsaTextAreaDisc" ).bind( "input" , function () { checkdata(); }); }); //here we check both radio button clicked and textbox filled with some information function checkdata() { if ($( "#LoginID" ).prop( "checked" ) && $( "#SIS_ID" ).prop( "checked" ) && $( "#eNtsaTextAreaDisc" ).val().length > 0) { $( "#btnNext" ).removeAttr( "disabled" ); } else { $( "#btnNext" ).attr( "disabled" , "disabled" ); } } Hope this would help you! Thanks!

Hi try below Jquery code snippet : var SIS_ID_VAL=''; $("input[name='SIS_ID']").click(function () { var txt = $("#LoginID").val(); SIS_ID_VAL=$(this).val(); if ($("#SIS_ID").is(":checked") && txt.length > 0 ) { $("#Next").removeAttr("disabled"); } else { $("#Next").attr("disabled", "disabled"); } }); $("#LoginID").keyup(function(){ var txt = $("#LoginID").val(); if (SIS_ID_VAL.length > 0 && txt.length > 0 ) { $("#Next").removeAttr("disabled"); } else { $("#Next").attr("disabled", "disabled"); } });
