We have a table for scanned signatures with a key field, text field, and media field. In Table view users cannot right-click the media field to bring up the “Load Image” option until they first click into the text field. In other words the cursor must be blinking in the text field in order for the right-click option to work on the media field.
This is the way it works now.
You first have to select the row, and than you can right-click it.
What you could do, is to present the media-field in a label. (So they don’t have the abbility to right-click) and make a button next to it, with a method that loads the media(blob) field.
something like this:
var filename = application.showFileOpenDialog()
if (filename)
{
mediafield = filename
}
This way, you have full-control, about everything.
Hope this helps.
