Custom upload forms

Hallo, I would like to design custom forms for file upload in FileManager - especially to change the options available when upload is not possible or fails for some reason. Is it possible to do that?

Hi Gian,


Greetings from Syncfusion support.


With the details you provided, we understand that you want to customize the error message for the FileManager component when an upload fails or is not possible. We would like to inform you that you can capture the error details of the upload operation failures and take any necessary actions using our OnError event, which will be invoked when the AJAX request fails. Based on the error details, you can design a custom form according to your application's needs.


Please refer to the shared details, and if you need any further assistance, kindly provide the following information:


- What type of data is being loaded in your project? Is it flat data or data with AJAX settings?

- Are you trying to use one of our listed providers or a custom provider? If you are using AJAX settings, please share code snippets from the backend service.

- If you have tried out any samples, please share the code snippets or the sample (including the events, property combinations, and methods you have utilized on both the client and server sides).

- How do you configure the custom forms or manage the display/change of the upload failure message?


This information will help us identify the exact use case in your environment. Your input will be invaluable in helping us understand your issue and providing a timely resolution.


Regards,

Leo Lavanya Dhanaraj
