Hello,
I have two linked datagrids one for installments and the child for invoice payments. I need to prevent users from changing the amount column or even the entire row of the invoice datagrid after it has been updated. Can any one help?

Thanks :)

How are you updating the data in the datagrid itself or do you update somewhere else and load it up in the datagrid. To lock the data grid in .net its the readonly= false

Thank you for replying. But the readonly will lock all the rows in the datagrid. I need to lock only the updated rows i.e. the rows where payment is recieved.:)
