I have just answered your support ticket on the subject, for convenience I will paste my answer here as well:
I am afraid that I cannot point you an example similar to the described one and its implementing would not be a trivial task. You could follow a similar logic in implementing it:
- upload the images via RadUpload or RadAsync pload to the desired location
- using the RadUpload/AsyncUpload API get the uploaded image and insert it into the next empty cell from your form (you will need to implement your custom logic here)
- Attach handlers to the image element's click event, where to show a hidden ImageEditor control, load the clicked image into it (via AJAX) and modify it into the control.
- in order to gather the edited images into one, you can use a logic, similar to the one implemented into this custom InsertImage dialog, but you will need to made some additional calculations on where exactly to put each image (in width and height).
