How To Delete Classic Report Row Without Page Submit In Oracle Apex Application

Oracle Apex Is Recognized As A Strong Tool In The Areas Of Effective Data Management And Interfaces That Are Easy For Users To Navigate. In This Guide, We Will Explore An Important Feature Of Oracle Apex Capability – The Procedure Of Removing Entries From A Report Without Having To Submit A Page. This Method Not Only Simplifies The User's Experience But Also Improves The Efficiency Of Your Oracle Apex Applications. Let's Examine The Ways To Accomplish This Effortlessly.

Understanding the Challenge

The Conventional Method

In The Past, Removing Rows From A Report In Oracle Apex Needed A Page Submission. Users Will Have To Choose Their Options, Send The Modifications, And Subsequently Wait For The Page To Refresh – A Procedure That May Consume Time And Interrupt Their Task Progress.

The Modern Approach

The Scenery Has Transformed, And User Anticipations Have Changed. Nowadays, Users Expect Instant Communications And Promptness. Removing Rows Without Submitting The Whole Webpage Conforms To These Anticipations, Offering A More Fluid And Active User Encounter.

Implementing Deletion Without Page Submission

1. Leveraging Dynamic Actions

Oracle Apex empowers developers with dynamic actions – a feature that enables the creation of actions based on specific events, without requiring page submissions. By harnessing this functionality, you can create a seamless deletion process.

2. Setting Up a Dynamic Action

Begin by identifying the report rows you want to make deletable. Create a dynamic action that triggers when a user interacts with these rows. This could be through a right-click context menu or a dedicated delete button.

3. Defining the Action

Within the dynamic action, specify the action you want to perform – in this case, deletion. Connect this action to the appropriate backend process responsible for deleting the selected row from the database.

4. Refreshing the Report Region

To ensure the user sees the updated data immediately, incorporate a step to refresh the report region. This step enhances the real-time experience and provides immediate visual feedback of the successful row deletion.

5. Testing and Optimization

As with any development process, thorough testing is crucial. Verify that the dynamic action works as intended, deleting the selected row without submitting the entire page. Optimize the process based on user feedback and performance metrics.

Steps How To Delete Report Row Without Page Submit In Oracle Apex

Create Region And Classic Report
Create A Item = P9_delrow
Use The Following Code Inside The Report Code

SELECT ID,
       USER_NAME,
       LATITUDE,
       LONGITUDE,
       LOC_DATE,
       '' Del
  from USER_LOC

4. Change The Type Of P9_DELROW Item = Link
5. Change link
Target =

javascript:deleteRowGlobal('#ID#','P9_DELROW')

Link Text =

<button class="t-Button t-Button--noLabel t-Button--icon t-Button--stretch lto21536390526165204_0 t-Button--hot" type="button" id="B21536" title="Remove" aria-label="Remove">
   <span class="t-Icon fa fa-trash-o" aria-hidden="true"></span>
 </button>

6. Create Dynamic Action
Name-Delete row Event—Custom - Custom Event
Custom Event
Link_Call Selection Type - Item
Item(s) - P9_DELROW
True Action—Execute Server-Side Code
Language = PL/SQL
PL/SQL Code =

BEGIN
    DELETE FROM USER_LOC
          WHERE id = :P9_DELROW;
END;

Items to Submit = P9_DELROW
True Action = Refresh
Affected Elements
Selection Type = Region
Region = Classic Report

7. Go To Function And Global Variable Declaration

function deleteRowGlobal(recordid, delitem) {
    apex.lang.addMessages({
        "APEX.DIALOG.OK": "Yes"
    });
    apex.lang.addMessages({
        "APEX.DIALOG.CANCEL": "No"
    });
    apex.message.confirm('Are you sure to remove this row?', function(okPressed) {
        if (okPressed) {
            // Delete it!
            apex.item(delitem).setValue(recordid);
            apex.event.trigger('#' + delitem, 'Link_Call', '');
            apex.message.showPageSuccess("One Record Removed....");
        }
    });
}
