Hello Swapnil,

In order to extract the old activity name you can try modifying the code like demonstrated below.

C#:

protected void RadGrid1_UpdateCommand(object sender, GridCommandEventArgs e)
    {
        GridEditableItem EditItem = e.Item as GridEditableItem;
        ....
        string OldActivityName = EditItem.OwnerTableView.Items[EditItem.ItemIndex]["ActivityName"].Text;
    }

Additionally I recommend examining this help article in which you can find helpful information on how to access the cells and rows in RadGrid.
