Why we need to do: –
The Control Break feature in Oracle APEX is essential for improving the usability and readability of Interactive Reports, especially when dealing with large datasets. It allows you to group data based on specific columns, making it easier for users to focus on related information. This is particularly useful in scenarios where horizontal scrolling is required, as it ensures that key headers or grouped data remain visible, enhancing navigation and accessibility. Additionally, Control Breaks help users analyze data more efficiently by presenting it in an organized and structured manner. By incorporating this feature, you not only improve the visual presentation of your reports but also provide a more seamless and professional user experience.
How do we solve:
Create a new page in Oracle APEX and choose Interactive Report as the page type. Define the data source for the report by specifying the SQL query or table that contains the required data. Once the report is created, you can organize the data using the Control Break feature. To apply this, go to the runtime environment, click on the Actions menu in the report toolbar, and select Data > Control Break. From there, choose the column by which you want to group the data. This will automatically group the rows based on the selected column, making the report more structured and easier to analyze.
Set Up Horizontal Scrollbar:-
Add a Dynamic Action for Page Load
Step 1: Go to the Page Designer for the Interactive Report page.
Step 2: Under the Dynamic Actions section, create a new Dynamic Action.
Name: Fix Horizontal Scroll
Event: Page Load
Action: Execute JavaScript Code
Step 3: Copy and paste the provided JavaScript code into the Code section.
JavaScript Code :-
The provided JavaScript code works as follows:
Identify Elements:
It targets the Interactive Report’s table container (.a-IRR-tableContainer) and table (.a-IRR-table) using a specific region ID.
var regionId = ‘#MY_REGION’;
A new div is created as a custom scroll-bar container (custom-scroll-bar-container).The scrollbar’s width is dynamically set to match the table width.Two scroll events are synchronized: one for the custom scrollbar and one for the table container.
This ensures that scrolling one element updates the other.
$(function () {
var regionId = ‘#MY_REGION’;
var tableContainer = $(regionId + ‘ .a-IRR-tableContainer’);
var table = $(regionId + ‘ .a-IRR-table’);
// Create the custom scrollbar container
var customScrollBar = $(‘<div class=”custom-scrollbar-container”></div>’).insertBefore(tableContainer);
var customScrollContent = $(‘<div></div>’).appendTo(customScrollBar);
// Set the width of the custom scrollbar content to match the table
customScrollContent.width(table.width());
// Sync the scroll positions between the table container and the custom scrollbar
customScrollBar.scroll(function () {
tableContainer.scrollLeft(customScrollBar.scrollLeft());
});
tableContainer.scroll(function () {
customScrollBar.scrollLeft(tableContainer.scrollLeft());
});
});
CSScode:-
.custom-scrollbar-container {
height: 20px;
overflow-x: auto;
overflow-y: hidden;
background: #f0f0f0;
border: 1px solid #ddd;
}
.custom-scrollbar-container div {
height: 20px;
}
Conclusion:
The Control Break feature in Oracle APEX Interactive Reports is a simple yet powerful way to organize and present data effectively. By grouping rows based on a specific column, you can improve the clarity and usability of your reports, especially when working with large datasets. Combining this feature with additional customization options, such as fixing scrollbars, enhances user navigation and ensures a professional, user-friendly experience. Leveraging these tools, you can create highly interactive and accessible reports tailored to meet diverse user needs.
