If iam not selecting a row and Clicking on that delete attachment button there is no alert as"Select one Row" and also if there is no row and if am clicking on delete attachment button ,in here too i didnt received the alert as " There is no Attachment". How to Fix this.

    Hi Prakya

    I have created a solution for you. It is based on creating the checkbox in the classic report then getting number of checked rows. Please check your demo


    1) Add STDID as PK column of your table STUDENT

    2) Write the SQL of the Standard Report

    select apex_item.checkbox(1,STDID,'UNCHECKED' ) as "CHECK",
      from STUDENT

    3) Create a hidden item to hold the checked rows count P6_CHECKEDCOUNT

    4) Using Component View, update the type of the column CHECK to be Standard Report Column

    5) Create a dynamic action on change of the jQuery selector td[headers="CHECK"] input

    - Execute JavaScript

    var checkedrowscount = $('td[headers="CHECK"] input:checked').length;

    6) Update the Delete Button to be Defined by Dynamic Action

    - Execute JavaScript

    var checkedcount = $v('P6_CHECKEDCOUNT');
    alert(checkedcount + ' row(s) checked');
    var checkedrowsarray =$('td[headers="CHECK"] input:checked');
    $.each(checkedrowsarray , function(index, val) {

    7) DELETE the checked rows

    You could achieve this final step by updating the above JS code to call PL/SQL of DELETE checked rows.
