This article explains how to implement a reusable character counter for text fields in Oracle APEX. The counter displays a live count of characters typed versus the maximum allowed length. It provides visual warnings (orange) and danger indicators (red) as the user approaches or reaches the limit. Paste the following function code at the page level (Function and Global Variable Declaration), or create a region in the Global Page using the Blank template. In that region, select Source and paste the function code enclosed within <script></script> tags.  function setPostTextCounter (itemId)  {     var item   = apex.item(itemId);     var inputEl = item.element;     var maxLen = inputEl.attr("maxlength") || 100;       var curLen = item.getValue().length;     var counterId = itemId + "_counter";     var postText = inputEl.siblings(".t-Form-itemText--post");     if (postText.length =...

Oracle APEX's Universal Theme provides a modern and clean user experience through features like floating (above) labels for page items.  These floating labels work seamlessly when users manually enter data, automatically moving the label above the field on focus or input.  However, a common UI issue appears when page item values are set Dynamically the label and the value overlap, resulting in a broken and confusing user interface. once the user focuses the affected item even once, the label immediately corrects itself and displays properly. When an issue is reported, several values are populated based on a single user input, causing the UI to appear misaligned and confusing for the end user. Here, I'll share a few tips to fix this issue. For example, employee details are populated based on the Employee name. In this case, the first True Action is used to set the values, and in the second True Action, paste the following code setTimeout(function () {   $("#P29_EMAIL,#P29_...

While browsing the Oracle APEX forum, I noticed a question from a user asking how to disable all other cells in an Interactive Grid row until the first cell has a value. In this blog, we will explore how to disable all other cells in an Interactive Grid row until the first cell contains a value. This approach helps enforce proper data flow, avoids incomplete or invalid records, and improves overall data integrity.  By implementing a simple client-side logic using JavaScript and Dynamic Actions, we can gain fine-grained control over row-level editing behavior in Oracle APEX. Step1: Create IG with static ID of EMP. Step2: Paste the following code in function global declaration. function setCellsToReadOnly()  { var grid = apex.region("EMP").widget().interactiveGrid("getViews", "grid"); if (!grid || !grid.model) { return; } var model = grid.model; model.forEach(function (record, index, id) { var meta = model.getRecordMetadata(id); var fields ...

In Oracle APEX, Interactive Grid column widths are usually fixed or manually adjusted.  However, in some scenarios, a static width may not be ideal—especially when the column data length varies significantly.  To improve readability and user experience, we can dynamically set the column width based on the actual data displayed. For example, consider the EMP table, where the ENAME column contains employee names of varying lengths.  Instead of assigning a fixed width, we can automatically adjust the column width so that it fits the longest value in the grid.  This ensures that the data is fully visible without unnecessary truncation or excessive whitespace. Step 1: Create an Interactive Grid and assign the static ID as EMP. Step 2: Paste the following JavaScript code in Execute JavaScript Code under Page Load. (function () {     var region = apex.region("EMP");     var ig$ = region.widget();     var gridView = ig$.interactiveGrid("getVie...
