"return old value" ... old value of TextBox or old value of DataGridView cell?
Where are you putting this code?

And that is what your code is doing at first glance. You didn't answer my question about "old value". What is actually happening with your code

Please check Data Source binding of DataGrid.

Datareader source will read in readonly feedforward type dataset no changes will save.

DataAdapator should have updatable binding, and you need to update Datagrid data back to database else changes will lost.

Simple solution is update database and refresh DataGrid
