In the Grid Popup Popup Editor in Toad 10.x, the Format Code button is missing.
This button was there in Toad 9.7.2 and previous versions.
Removed due to an OCI bug preventing editing of XML data. Add an external XML editor from Options | Executables.
1. Download an external XML Editor.
2. Add the external XML Editor from View | Toad Options | Executables - browse for the XML Editor executable in the XML Editor field.
3. To save changes to database, once data is changed via XML Editor, copy and paste data into an Update/Insert statement to be executed in Toad.
