Managing Application Navigation Preview
Objectives After completing this lesson, you should be able to: Differentiate between various navigation objects (tabs, breadcrumbs, lists, navigation bar entries, and trees) Build a hierarchical list with images Build a database-driven navigation report Build a site map Add a dashboard Incorporate security into navigation Link interactive reports Manage feedback 3-2
3-3 Navigation Choices 3 1 4 2
3-4 Building a Hierarchical List with Images
Building a Hierarchical List with Images Steps 1. Update the list with the desired sublist items. 2. Identify and upload the images to include. 3. Change the template of the list region. 4. Change navigation region settings. 5. Associate an image with a list item. 3-5
Building a Database-Driven Navigation Report This report is used to navigate between pages by using links defined against values in the database. 1. Create a report based on a column. 2. Create a link to page and pass ID value. 3-6
Building a Site Map A site map is used to navigate between pages by page title. 1. Create a page group with the pages you want to appear in the site map. 2. From Activity, create SQL from the APEX_APPLICATION_PAGES view. 3. Create a report that shows the page name. 4. Create a link from the item to #PAGE_ID#. 5. Modify the report to use the desired templates. 3-7
Adding a Navigation Bar Entry To access the site map, create a navigation bar entry: 1. From Shared Components, select Navigation Bar Entry. 2. Click Create. 3. Select From Scratch and click Next. 4. Select Navigation to URL and click Next. 5. Enter Site Map for Entry Label click Next. 6. Select the site map page from the Page drop-down list and click Next. 7. Click Create. 3-8
Enforcing Authorization on Your Site Map Showing an entry on the site map based on authorization requires the following: 1. Create a function that checks for authorization. 2. Update the SQL query on the report to check whether the function is true. Administrator Developer 3-9
3-10 Adding a Dashboard Page A dashboard page provides a dynamic overview of your application.
3-11 Linking Interactive Report Regions Provide a declarative filter where value is Passed from one interactive report region to another.

Building Custom Tabular Forms
Objectives After completing this lesson, you should be able to: Build a custom tabular form Add validations to your tabular form Manage changes to the tabular form by using collections 4-2
4-3 What Is a Tabular Form? A tabular form allows users to update multiple rows in a table concurrently from a single page. Declarative Manual
Building a Tabular Form Manually Build a SQL report. Create an Update button. Add a process to perform the update. 4-4
4-5 SQL Report Query Uses the APEX_ITEM API to create a query. SELECT apex_item.hidden(1,employee_id) apex_item.display_and_save(2,last_name) last_name, apex_item.text(3,email,8) email, apex_item.date_popup(4,null,hire_date,'dd-mon-yyyy',10,null,null, lpad(to_char(rownum),4,'0')) hiredate, apex_item.select_list_from_query(5,job_id,'select distinct job_id, job_id from oehr_employees',10) job, apex_item.text(6,salary,6) salary, apex_item.text(7,commission_pct,6) commission, apex_item.popupkey_from_query(8,manager_id,'select last_name, employee_id from oehr_employees',10) manager, apex_item.select_list_from_query(10,department_id,'select department_name, department_id from oehr_departments',10) dname FROM oehr_employees
4-7 PL/SQL Process: Using the APEX_APPLICATION API Create a PL/SQL process with the following code: for i in 1..apex_application.g_f01.count loop update oehr_employees set email = apex_application.g_f03(i), hire_date = apex_application.g_f04(i), job_id = apex_application.g_f05(i), salary = apex_application.g_f06(i), commission_pct = apex_application.g_f07(i), manager_id = replace(apex_application.g_f08(i),'%' 'null%',null), department_id = replace(apex_application.g_f10(i),'%' 'null%',null) where employee_id = apex_application.g_f01(i); end loop;
4-8 Not Null PL/SQL Validation Ensures that valid values are entered before the data is updated in the database After the error message is displayed, click Back in your browser to return to the tabular form.
4-9 Adding a Not Null PL/SQL Validation Page-level PL/SQL validation with Function Returning Error Text on the Error page FOR i IN 1..apex_application.g_f01.count LOOP IF apex_application.g_f01(i) IS NOT NULL THEN IF apex_application.g_f03(i) IS NULL THEN RETURN 'Email must have some value.'; END IF; IF apex_application.g_f04(i) IS NULL THEN RETURN 'Hire Date must have some value.'; END IF; IF apex_application.g_f06(i) IS NULL THEN RETURN 'Salary must have some value.'; END IF; END IF; END LOOP;
Creating and Using a Collection on a Tabular Form 1. Create a process to load the collection. 2. Create a query against the collection. 3. Modify the report attributes. 4. Create a button and process to add a row to the collection. 5. Create a process to update the collection. 6. Create a button and process to delete a row from the collection. 7. Update the database from the collection. 8. Change the validation to use the collection. 4-10
Defining Client-Side Behaviors
Objectives After completing this lesson, you should be able to: Describe dynamic actions Explain the two types of dynamic actions: standard and advanced Create advanced dynamic actions to define complex clientside behavior such as the following: Changing the class when an item is null Disabling a button when an item is null Highlighting an item when the value of another item changes Setting the value of an item when another item changes Deleting and re-creating a row in a report 5-2
Dynamic Actions Use dynamic actions to define complex client-side behavior declaratively. Two types of dynamic actions: Standard Advanced Example of using a standard dynamic action Example of using an advanced dynamic action 5-3
Creating and Using Advanced Dynamic Actions: Examples This lesson covers the following examples of creating and using advanced dynamic actions in Application Express. Changing the class when an item is null Disabling a button when an item is null Highlighting an item when the value of another item changes Setting the value of an item when another item changes Deleting and re-creating a row in a report 5-4
5-5 Changing the Class When an Item Is Null A red border is applied when a user leaves the Last Name field empty.
5-6 Disabling a Button When an Item Is Null Last Name and Salary are not null and Apply Changes button is enabled. Last Name is null and Apply Changes button is disabled. Salary is null and Apply Changes button is disabled.
5-7 Highlighting an Item When the Value of Another Item Changes Austin Selecting a department id refreshes the manager id select list. The Manager Id field is highlighted when refreshed.
5-8 Setting the Value of an Item When Another Item Changes Job Id changes the commission percentage. Salary changes the commission percentage.
5-9 Deleting and Re-Creating a Row in a Report The first row is deleted. To re-create, click Recreate Employees.
5-10 Refreshing the Data in a Report Using Custom Filters Filtering the report based on department Filtering the report based on department and job
