Hi Chen,
Please accept my sincere apologies for not being clear enough in my previous answer.
RadImageEditor applies modifications made to the actual image file using callbacks. Most of the commands, except AddText, Crop and InsertImage, initially are only visualized on the client and are stored in a queue, and when a server-side Save event is triggered all the stored commands get applied to the actual image file.
The RadImageEditor's client-side method applyChangesOnServer() is triggering the ImageChanging server-side event and can be used to manually force the modifications that are only visualized at this point to be actually applied to the editableImage.
Now regarding your second question, you can modify the Save command to avoid the dialog and directly save the image on the server by handling the
OnClientCommandExecuting client-side event of RadImageEditor, e.g.:
You can find detailed information regarding the RadImageEditor's client-side API in our
online documentation.
Kind regards,
