I have following requirements to get done.

Add unbound column for "Edit" button in each row, preferly at the last column.

Once user clicks "Edit" that row is now editable, but only few columns are allowed to be edited.  Also the "edit" button now becomes "Cancel" so that user may cancel that particular row out of edit mode, restoring the original value.

User may choose to edit one or more rows so it keeps multiple rows in edit mode.

Button outside of the grid will trigger the rows in edit mode to be updated.

I look everywhere for training video but couldn't find any that will do "edit" row.  If you know of any helpful video link, let me know.

TIA.

Fyi, the grid is bound at runtime.  The UltraGrid version is 7.1 and we do have the latest version with license.  We would like to keep the 7.1 in place if possible.
