Usage in Code

C# / .NET

You can create a constants class in your project:

EventHandlerEvents.cs
public class EventHandlerEvents
{
    // Form Events
    public const string OnCancel = "ONCANCEL";
    public const string OnDelete = "ONDELETE";
    public const string OnDownload = "ONDOWNLOAD";
    public const string OnChange = "ONCHANGE";
    public const string OnClick = "ONCLICK";
    public const string OnInit = "ONINIT";
    public const string OnRefresh = "ONREFRESH";
    public const string OnSave = "ONSAVE";

    // Datatable Events
    public const string OnTableRunActionEvent = "ONTABLERUNACTIONEVENT";
    public const string OnTableRunBatchActionEvent = "ONTABLERUNBATCHACTIONEVENT";
    public const string OnTableEditRunActionEvent = "ONTABLEEDITRUNACTIONEVENT";
    public const string OnTableLoadData = "ONTABLELOADDATA";
    public const string OnTableEditLoadData = "ONTABLEEDITLOADDATA";
    public const string OnTableCreateRecordEvent = "ONTABLECREATERECORDEVENT";
    public const string OnTableSelectRowEvent = "ONTABLESELECTROWEVENT";

    // Folder Events
    public const string OnFolderCreateRecordEvent = "ONFOLDERCREATERECORDEVENT";
    public const string OnFolderEditRecordEvent = "ONFOLDEREDITRECORDEVENT";
    public const string OnFolderShareRecordEvent = "ONFOLDERSHARERECORDEVENT";
    public const string OnFoldersLoadData = "ONFOLDERSLOADDATA";

    // File Upload Events
    public const string OnFileUpload = "ONFILEUPLOAD";
    public const string OnFileUploadCreateDocumentEvent = "ONFILEUPLOADCREATEDOCUMENT";

    // Print Events
    public const string OnPrint = "ONPRINT";
    public const string OnPrintReturnContents = "ONPRINTRETURNCONTENTS";

    // Checkbox Events
    public const string OnRowCheckbox = "ONROWCHECKBOX";

    // Signature Events
    public const string OnStartSignProcess = "ONSTARTSIGNPROCESS";
    public const string OnFinishSignProcess = "ONFINISHSIGNPROCESS";

    // Template Events
    public const string OnLoadNewRecordTemplates = "ONLOADNEWRECORDTEMPLATES";

    // Advanced Events
    public const string OnDirectRunFormEvent = "ONDIRECTRUNFORMEVENT";
    public const string OnGetCustomResponse = "ONGETCUSTOMRESPONSE";
}

Usage Example:

[HttpPost("runevent")]
public async Task<IActionResult> RunEvent([FromBody] JsonElement requestBody)
{
    var widgetName = requestBody.GetProperty("widgetName").GetString()?.ToUpper();
    var eventType = requestBody.GetProperty("widgetEvent").GetString()?.ToUpper();

    // Use constants instead of magic strings
    if (widgetName == "savebtn" && eventType == EventHandlerEvents.OnClick)
    {
        // Handle save button click
    }
    else if (eventType == EventHandlerEvents.OnTableLoadData)
    {
        // Handle table data loading
    }
    else if (eventType == EventHandlerEvents.OnFileUploadCreateDocumentEvent)
    {
        // Handle file upload
    }

    return Ok(response);
}

PHP

Create a constants class:

EventHandlerEvents.php
<?php

class EventHandlerEvents
{
    // Form Events
    const OnCancel = 'ONCANCEL';
    const OnDelete = 'ONDELETE';
    const OnDownload = 'ONDOWNLOAD';
    const OnChange = 'ONCHANGE';
    const OnClick = 'ONCLICK';
    const OnInit = 'ONINIT';
    const OnRefresh = 'ONREFRESH';
    const OnSave = 'ONSAVE';

    // Datatable Events
    const OnTableRunActionEvent = 'ONTABLERUNACTIONEVENT';
    const OnTableRunBatchActionEvent = 'ONTABLERUNBATCHACTIONEVENT';
    const OnTableEditRunActionEvent = 'ONTABLEEDITRUNACTIONEVENT';
    const OnTableLoadData = 'ONTABLELOADDATA';
    const OnTableEditLoadData = 'ONTABLEEDITLOADDATA';
    const OnTableCreateRecordEvent = 'ONTABLECREATERECORDEVENT';
    const OnTableSelectRowEvent = 'ONTABLESELECTROWEVENT';

    // Folder Events
    const OnFolderCreateRecordEvent = 'ONFOLDERCREATERECORDEVENT';
    const OnFolderEditRecordEvent = 'ONFOLDEREDITRECORDEVENT';
    const OnFolderShareRecordEvent = 'ONFOLDERSHARERECORDEVENT';
    const OnFoldersLoadData = 'ONFOLDERSLOADDATA';

    // File Upload Events
    const OnFileUpload = 'ONFILEUPLOAD';
    const OnFileUploadCreateDocumentEvent = 'ONFILEUPLOADCREATEDOCUMENT';

    // Print Events
    const OnPrint = 'ONPRINT';
    const OnPrintReturnContents = 'ONPRINTRETURNCONTENTS';

    // Checkbox Events
    const OnRowCheckbox = 'ONROWCHECKBOX';

    // Signature Events
    const OnStartSignProcess = 'ONSTARTSIGNPROCESS';
    const OnFinishSignProcess = 'ONFINISHSIGNPROCESS';

    // Template Events
    const OnLoadNewRecordTemplates = 'ONLOADNEWRECORDTEMPLATES';

    // Advanced Events
    const OnDirectRunFormEvent = 'ONDIRECTRUNFORMEVENT';
    const OnGetCustomResponse = 'ONGETCUSTOMRESPONSE';
}

Usage Example:

public function runEvent(Request $request) {
    $requestData = $request->json()->all();
    $widgetName = strtoupper($requestData['widgetName'] ?? '');
    $eventType = strtoupper($requestData['widgetEvent'] ?? '');

    // Use constants instead of magic strings
    if ($widgetName === 'savebtn' && $eventType === EventHandlerEvents::OnClick) {
        // Handle save button click
    }
    elseif ($eventType === EventHandlerEvents::OnTableLoadData) {
        // Handle table data loading
    }
    elseif ($eventType === EventHandlerEvents::OnFileUploadCreateDocumentEvent) {
        // Handle file upload
    }

    return response()->json($response);
}

Event Categorization

User Interaction Events

Events triggered directly by user actions:

OnClick, OnChange, OnCancel, OnDelete, OnDownload

Data Loading Events

Events that require loading data:

OnInit, OnTableLoadData, OnTableEditLoadData, OnFoldersLoadData

Data Modification Events

Events that modify data:

OnSave, OnTableRunActionEvent, OnTableEditRunActionEvent, OnTableRunBatchActionEvent

File Operations

Events related to file handling:

OnFileUpload, OnFileUploadCreateDocumentEvent, OnDownload

Workflow Events

Events for business processes:

OnStartSignProcess, OnFinishSignProcess

Best Practices

Use Constants - Always use constants instead of hardcoded strings
Case Insensitive - Convert event types to uppercase for comparison
Event Grouping - Group related events in your handler for better organization
Validation - Always validate that required data is present for each event type
Error Handling - Implement proper error handling for each event type
