Hi sam user have no idea what is enter in textbox suppose user enter the some white space your condition is false. I think this a not a good idea for validate the value and one more thing i can't understand what you want disabled or hide the textbox and another control. checked like this Remove the white space in jquery try this code $.trim(control id) Enable or Disabled control if($('# txtfrom2 ').val()!='null'||$('#txtform2').val()!='') { ValidatorEnable ( ' '  false ); } else { ValidatorEnable ( ' '  false ); } Hide and unhide control in jquery if($.trim($('# txtfrom2 ').val())!='null'||$.trim($('#txtform2').val())!='') { $('#controlId').hide(); } else { $('#controlId').show(); } *jsb
