UPDATED:
Starting with version v2015 vol 1 (v15.1), this functionality is available out of the box. Simply set the GridViewDataBinaryImageColumn.PropertiesBinaryImage.EditingSettings.Enabled property to True to activate it. Please refer to the ASP.NET Data Grid - Binary Image Editor (Coming soon in v15.1) blog post and the Binary Image Column Editing demo for more information.
If you have version v15.1+ available, consider using the built-in functionality instead of the approach detailed below.
This example shows how to use ASPxUploadControl on the ASPxGridView's Edit Form to preview an image before performing data update.

So do i have to create a custom edit form just to add an an image? Not sure why the software doesn't generate the upload code for you.
I am familiar with WinForms but the ASP model is new to me I tried to follow the example below but received an error on 'ConvertOleObjectToByteArray' I am sure there is something I need to include.
Any help in beginners terms for customizing would be greatly appreciated.

Hello Rosario,
To process your recent post more efficiently, I created a separate ticket on your behalf: T254295: E2933 - How the ucImage_FileUploadComplete and callbackPanel_Callback events are used. This ticket is currently in our processing queue. Our team will address it as soon as we have any updates.
Do you have a code sample in vb.net with asp.net just with .PDF file?
