Please add the option in Row_CustomAction that has ability to receive the input parameter from Modal dialog.
The idea is as follows:
- The end-users click the button that will trigger the Modal dialog to be shown up, and they have to input something in it,
- They click on Submit button in that Modal dialog, and this input param will be supplied into code in Row_CustomAction server event,
- The rest of process will be done by the code in Row_CustomAction server event just like the existing condition.
