Thank you for your help.
It is working.

Hi, I am trying to change the edit property of the Cell in the DataGrid for primary key column.
I want to disable the edit if the row exists, but the new row needs to be editable for the key column.

Please give an advice how to change the cell property in the DataGrid.
Thank you.

I'm not sure if here is the correct place for my question.
I would like to purchase the license of a product, and I need to know if it is possible for my project.

1. Is it possible to import the json data into datagrid in the memory?
2. How do I retrieve data in the datagrid by button click event instead of having it appear automatically?
3. How do I use file upload process?

Thank you.
