How can i get the previous value of a control when editing a data grid?

[Blake Versiga]

When editing a datagrid (C#)
I need to know if the user changed the value of cell AND what the previous
value was.

Is this possible? If so how do I get the previous value or at least if the
cell has changed?

TIA
Blake

Hi Blake,

In DataGrid.UpdateCommand, DataGrid.EditItemIndex can be retrieved before
it is set to -1. Therefore, we can use
dataset.Tables[0].Rows[DataGrid.EditItemIndex][i] to get the previous value
of the cell. Then, we can check if the user changed the value of the cell.

The following link may be helpful:

Does this answer your question? Please let me know if you need more
information.

Best regards,
Lewis
