Hi Mahesh,  
 
Greetings from Syncfusion support. 
 
We have checked your reported problem with FileManager component. Yes, it is possible to send the additional parameter from client-side to  the server-side API controller methods in the client-side events of FileManager component. 
 
SQL FileOperations and upload:  
 
You can send the Send additional parameter in upload and file operations in SQL using beforeSend event of FileManager component. 
 
Refer the belo2 code snippet. 
@Html.EJS().FileManager("filemanager").BeforeSend("beforeSend").BeforeDownload("beforeDownload").AjaxSettings(new Syncfusion.EJ2.FileManager.FileManagerAjaxSettings 
{ 
}).Render() 
 
<script> 
    function beforeSend(args) { 
         var data = JSON.parse(args.ajaxSettings.data);  
          if (args.action == "Upload") {  
            // Allow custom data for upload operations   
            data.push({ 'username': "user1" });  
            args.ajaxSettings.data = JSON.stringify(data);  
         } 
         else { 
          // Add custom parameter column  
            data["username"] = "user1";  
          // Add custom parameter in ajax settings  
            args.ajaxSettings.data = JSON.stringify(data);  
         } 
    } 
 
You can add the custom class in controller part and use the class in fileOperations.  
 
    public class FileManagerDirectoryContent1 
    {  
        public string username { get; set; } 
        public FileManagerDirectoryContent[] Data { get; set; } 
        public bool ShowHiddenItems { get; set; } 
   } 
public object SQLFileOperations([FromBody] FileManagerDirectoryContent1 args) 
        { 
            if ((args.Action == "delete" || args.Action == "rename") && ((args.TargetPath == null) && (args.Path == ""))) 
            { 
                FileManagerResponse response = new FileManagerResponse(); 
                response.Error = new ErrorDetails { Code = "403", Message = "Restricted to modify the root folder." }; 
                return operation.ToCamelCase(response); 
            } 
} 
 
Refer the below screenshot.  
 
 
 
Download : 
 
You can send the addition parameters od Download operations using beforeDownload operations. 
 
Refer the below code snippet. 
 
@Html.EJS().FileManager("filemanager").BeforeSend("beforeSend").BeforeDownload("beforeDownload").AjaxSettings(new Syncfusion.EJ2.FileManager.FileManagerAjaxSettings 
{ 
}).Render() 
<script> 
    function beforeDownload(args) { 
         var includeCustomAttribute = args.data; 
         includeCustomAttribute.username = "user1"; 
         args.data = includeCustomAttribute; 
   } 
</script> 
 
Refer the below screenshot.

Hello, Thanks for the update but I would like to know how to avoid passing those parameters using " beforeSend " function of component.html file ? because that will be available in view source if unwanted user wants to hack it.

Hi Kaustubh,


Greetings from Syncfusion support.


As per the shared details, we understand that you need to avoid passing those parameters using the "beforeSend " event. In our previous update, we have sent JWT token from client end to perform customizations at server end. For getting client-side login user details in server side without sending it from client end, we suggest you refer to refer the below blob to get the details directly at server end and achieve your requirements.
