*** The parts I want are as follows.**
- Import the local Excel file.
- Modify specific cells in the file.
- Bind the modified file to the flexgrid.
*** The present problem**
I’ve finished importing and modifying the local Excel file.
However, there is a problem that the modified data is bound in the binding part and then the original data is bound again.
(Binding is done twice)
Please refer to the code below
Please refer to the .zip file for xlsx data
- PS.
The ContentsLayout part is for screen layout.
